Just for the record I can create wiki's but I think it would be more practical if it would be a part of the elemental environment. Also with the same user id and passwords of the forum users.
Because then you can have your mods uploaded to the site and all the documentation in the wiki. Also because its part of the site you can give personal pages that can only be edited by the owners.
Yes I am aware that the idea behind wiki's is that they are public.. but that is not always practical..
