There's a few of us around here.
Methodists typically practice open communion, so being able to participate isn't something you should need to worry about.
If you want doctrinal stances, then you could look at these:

Another resource for generally-Wesleyan, but not necessarily Methodist, stances is

Off the top of my head, the thing I'd likely say makes Methodism distinct are the views of grace. This also has ties into the fact that the vast vast majority of Methodists are Arminian (or more precisely, Wesleyan-Arminian), but there are some Reformed Methodists in Wales. It also undercuts a lot of other positions that you might see Methodists take in regard to social or theological issues. Grace is seen as threefold: prevenient (which God gives to all), justifying (essentially, conversion), and sanctifying (growth in faith). Salvation can be lost, but that is generally seen as a result of constant and vehement rejection and unrepentant behavior. Salvation is also likely viewed as being a continual process than a one-time event (this is where sanctifying grace really figures), but one can have assurance of their salvation. Baptism and Communion are recognized as sacraments.
Historically, Methodism was a movement in the Church of England in the 1700s. John Wesley was an Anglican priest who put a higher emphasis on study of Scripture and reaching out into the community - visiting prisons as chaplains, feeding the poor, and so on. Those that followed this example were pejoratively called Methodists, a title which either got reclaimed or eventually just stuck and gradually lost its teeth.
What caused it to split in the late 1700s was politics - both within the Anglican Church, as Methodists were often seen as radicals, and within the British Empire, as the initial schism occurred between the Church of England and American Methodists because there was a shortage of priests due to the American Revolution (and anti-British sentiment on the American side in the wake of that event which wouldn't jive too well with clergy that acknowledge the British Monarch). Despite this, Methodism has stayed rather theologically close to Anglicanism, just without the Calvinist or Royalist parts. The Methodist Articles of Religion are an abridged version of the Thirty-Nine Articles of the Church of England that Wesley prepared for those in the Colonies (with a couple of later additions).
Also a little paradoxically, Wesley himself remained in the Anglican Church until he died, and both he and his brother Charles are recognized on the liturgical calendars of several churches in the Anglican Communion (or perhaps the Communion as a whole, but I can't say that definitively). There are also parishes within the Church of England that can likely be described as being Wesleyan.
Later exposition of Wesley's sermons and notes is often seen to point toward a position known as the Wesleyan Quadrilateral: Scripture, Tradition, Reason, and Experience, where Scripture is primary but the other three are necessary to use as lenses to make sure that the interpretation is correct. Depending on which Methodist you ask, this could be seen as being Prima Scriptura rather than the typical Protestant position of Sola Scriptura.
In many other areas of theology or social/national politics, you can see a large breadth of positions in Methodism. This is partially because there are only a few things (like the use of historical creeds) that Methodists could be seen as dogmatic about, and those things are the general points that all Christians have in common. The Wesleyan influence plays into some positions, but not necessarily all of them, and aside from things that would be seen as distinctively Methodist (like the views of grace or feasibly the Quadrilateral), it's left between the believer and God.
There are a couple of things that you won't see much of in Methodism, though. One of which is a heavy emphasis on the end times - Methodists are far more concerned with the present day and fulfilling the role of steward (as a side point, you probably will not see very many Dispensationalists either, although it can't be completely ruled out due to geographical influence from other churches or parishoners just not being very well-versed in their eschatological views), so end times stuff isn't brought up too often, and when it is, there may not be too much fire and brimstone. The other is that Methodists are not very apt to try and mix national politics and religion - you might see certain social causes advocated since that sort of thing is historically a focus of Methodism (and to wit, the phrase 'social justice' was largely used in reference to Wesleyan attitudes toward social outreach and reform long before it was ever demonized by right-wing pundits), but there will probably not be much in the way of campaigning from the pulpit. Individual Methodists may be political, but the churches themselves tend to be apolitical.
