Hi Dirk,
Feel free to reply either here in the forums or directly to me at my first name @itcrossing.com. I'm interested to know if you're already using the wiki module and how you're using it. If there's something online that I can see, it will help me get a better feel for the common usage scenarios for this module.
We're certainly interested in creating a provider for this module.
Thanks,
Don
PS This reply was written in Windows Live Writer with the new metaPost Forum provider that's due out any day now. We're fixing some last minute issues before it's ready to be shipped. Also, my apologies to those who have subscribed to the forum for the extra email messages being sent related to deleting test messages. This is one of the issues that we're working to resolve this weekend.
