About 3 years ago I think I used Match or OKCupid? Can't remember which. One of the two of them had hundreds of questions over different areas that you could answer, and also leave explanatory notes, I liked that. Then it would calc a compatibility score, and you could see the other persons answers, I believe, which was kind of nice.
Of course, if you see someone you really like, there's always the temptation to "tweak" the answers you give or even the questions you answer. "Hi! I see we now have 99% compatibility! You should get to know me!" lol. Yeah, watch out for that.
Maybe chat and after chatting for a while go for coffee (Covid depending, I can't imagine OLD in a Covid world lol)
Be prepared for people to just not respond or ignore you
Be prepared for people to get PO'd if you don't respond or ignore them
Be prepared for people to not be what you are looking for
Be prepared to not be what other people are looking for
And, all of that's OK I guess.
Most people are looking for a friend, whether they know it or not
And most people are looking for Christ, whether they know it or not
Just make sure you aren't one of those who aren't
