I have a few silly suggestions, but will state them nonetheless. Feel free to critique...
A: The "Doorbell" feature. I don't view it as completely fair to be prohibited from viewing other Prides. I think perhaps someone can come into a pride by "ringing the doorbell."
Either through PMs or something: "_______ has rung the doorbell! Allow _______ to come in?" If you're looking to switch prides, you must know which one will suit you best!
And I believe, and this was brought to my attention by DragonStar, the Pride leaders should create ranks/titles to achieve after posting a certain number of times OR for winning quizzes, etc. But I don't think there should be set ranks. I think you should let the leader create about 5-15 ranks. So when someone accomplishes something, they don't get a default rank but can choose from around 3.
