The way I like to go about it

is I'll pick a sub-profile and click watch on all threads I'm in, across all alts. Usually my main one where I'm more likely to catch a notification. You know, that account you're always on when you have nothing better to do and just sit around hitting the refresh button every other minute
in case something interesting will happen
I've also bookmarked the "New posts" page in my news feed and filtered it to show only watched threads. So if the mentions, the discord tags, or my mindless refreshing has me miss (or forget) a post, I'm one click away from a neat overview of all my current rp threads where I can see who posted last and when. I try to keep it clean, and unfollow once they're done or finished.
