I'm looking for a guestbook like system, but it has to allow non-registered users to post on it also. And I need this to be possible for every user to have. I've already went through a lot of systems like this- jomwall,profile book for example but none seem to be working fine for me.
Any ideas will be greatly appreciated!


P.S. I would also like to know if the user list can be in 2 columns instead of only one.
