Welcome to IdCast! It is a bit messy, it changes all the time, it is very bright and white, and that's the way we like it!
IdCast is a project of Interaction Design Lab. If you want IdCast specific help, you will have to wait for WalterAprile to write it, and he is a very lazy man.
If you want general help on how to work this whole wiki craziness, you can read the HelpContents page. Of particular interest and usefulness are: HelpForBeginners, HelpOnPageCreation, HelpOnUserPreferences and HelpOnEditing.
