Hi,
We are currently in the process of making the necessary changes to start charging for access (and I think this could seriously increase our income
). The way we are doing it is by adding a lot of additional features (PhotoPost, ReviewPost, chatroom, email, etc) and offer people the chance to upgrade.
Those that do not wish to pay will continue to be able to do everything they can do now (with the exception of search, which we will only make available to Premium Users). Those that pay get all the additional features.
Our main reasoning for going this route is that people resent having things taken away. It is also easier to justify charging more if you in return give users much more features.
Sanuk!
