With do it your self forums, we can choose the sub forums we want to read and ignore the others. Therefore we are designing our own experience of CF.
If I only want to read golden eagles section, as well as widows and mature singles, I can choose to put on ignore, all the other sub forums in that forum.
They would also stay permanently locked that way, unless we want to change our forum settings for each forum to something else we decide we want to see or unsee.
