Just a curiosity about the Wiki linked in the forums here, I think the maintenance of the one here on github may be easier (https://github.com/adventuregamestudio/ags-manual). Is there interest in linking it here somewhere? Maybe some interesting knowledge from the original wiki could be migrated to that other one.
The current wiki is tied into the forums. It's the same reason we host our own bug tracker. Non technical people aren't very likely to create a separate account on a developers' site just to make an edit to a wiki page about a random AGS game. And if we're talking about an external wiki, why not use Wikia, which is made for games wikis...
Since this threads exists:
when I try to edit a wiki article, PHP complains about missing the Class CaptchaTriggers.
