Looking for help (forum-rping, FCs, finding a roleplay)

Hello! Newb looking for help here.

I've written with people before, but never in an online forum style (more than one-on-one writing). What kind of rules/etiquette are expected in forums, where you're dealing with more than one other person? And how can I ease myself into this setting without stepping on people's toes or undermining someone's hard work?

Also, I've looked at a few roleplays on here, though I only just came to the RPG. I've noticed "FCs", or animated gifs of actors in some character listings; what does FC stand for, what are their functions/why are they needed, and how common are they in the forums?

And finally, how do you find a roleplay that suits your needs? Is there a way to search multiple tags at once to find a thread or forum right for you?
