Re: The Discuss Button on the Wiki Page Produces the Error Msg "No forum indicated"
I'm not sure if punctuation in general is ruled out, but the appostrophe is apparently problematic for some reason (maybe due to messing up the script or due to url encoding problems). I have no idea if this is related or not, but there's a wiki admin option for using non-English wiki page names, and you could change that to "complete" (if I recall correctly) to see if it makes a difference.
As far as I know, there's no way to indicate more than one forum for discussing wiki pages.
I also get the "Unknown group" error message. Apparently that's a bug — or something that wasn't completed, etc. You can just set permissions as needed on the forum admin page.
