I'm reviving this 2-years old thread. I too believe an OmniFocus wiki would be *very* useful. While forums, like this one, are great for questions, wikis are great for collaborative answers!! (well, not exactly true, but wikis are great for extended collaborative documentation, and this is something we seriously need for OF, it could even include documentation of user-generated AppleScripts)
Scot: the
wiki you built is down. Do you plan to revive and maintain it?
I'll send a feature request to the Ninjas specifically asking for an "OmniFocus wiki". I encourage you to do so too, if you want it to happen! :-)
