I'd like to use w-a to do more than just basic discussion forums. I'd like to use it to handle slashdot style news for the home page, standard discussion forums, and an amazon style book review system (for example). In each case, the fields captured by a post would need to be slightly different (book title, book ISBN, book rating, etc VS news date, news time, etc).
Can w-a handle each top-level forum having both different visual schemes AS WELL AS different data schemas? Or, perhaps would I have to set up multiple "instances" of w-a?
Any insight on how to make this happen would be greatly appreciated.
