I think there should be a feature where instead of buying a whole membership just so you can go in chat, have the book feature, forum feature, etc... That you should be able to buy them seperated for a certain amount of time.

Ex. Sally wants to write a book, but doesn't have money and she doesn't want all the other features just wants the feature to write her book on here. Well if you had that button it wouldn't turn Sally away to go to another site and type it free.

Not saying you should drop the whole membership aspect of it, but should have a seperated feature thing where they can buy certain features.
