6: Be active and open.

I guess I haven't added this yet since it was already mentioned in my "How to Become Popular" book. Please, if you want to be a successful roleplayer, log in and reply to people/roleplaying partners often. I recommend at least once a day, but once or twice a week is fine, too.

That is to say, if a time comes where you can't login for at least a week, don't worry too much about it. Only a month or more would affect you, but you can recover (not that recovering is too easy).

Make sure you add that you're up for roleplaying anytime in your description! Fellow roleplayers will open up to you for that.

Roleplay with any person that brings up roleplaying with you, no matter what. You can make an exception if your roleplaying partner can't even roleplay without sounding like an immature six-year-old.

Practice a bit of writing, too! The better skilled you are at writing, the higher the chance people will like roleplaying with you! ^-^ (basically, staying in character, being active, and writing at least decently are the three keys to roleplaying in pm/roleplay books)

Good writing isn't required too much for roleplayer profiles, though. Just learn to talk like your character. 

Oh yeah, and it helps if you're brave enough to approach a random roleplayer/roleplayer profile and ask to roleplay with them! Most would appreciate you roleplaying with them, so don't worry about being bothersome.
