I'm still thinking of ways to notify visitors of updates to the wiki, since the wiki is not directly tied to the WordPress display mechanisms.
Anyhow, check out my wiki and see if there's anything there you think I should include. It's not complete at all, but there is a small framework of the type of thing that I'd like to include.
Also, I'm going to update the software soon so that people can leave comments. That should be fun.
How about and RSS feed for your Wiki? Then you could display it with something like CaRP.
That's probably a good idea. Maybe I'll implement that and read my own RSS for displaying updates.
