Can I edit this wiki post?
Yes! Everybody except Level 0 (=New). You can recognize a wiki post by its “Edit” button on the lower right.
Can I create a Wiki or FAQ as a normal user (not being an Admin)?
Yes! The default setting is that users with Trust Level 3 (=Regular) may turn their posts into a wiki post. But this setting (
min trust to allow self wiki) may be lowered to 1 (=Basic) by the Site Admin so that “Basic” or higher users may be able to do this.
And then others may edit my post?
Yes! Everybody except Level 0 (=New).
And the wiki post will be editable forever?
Yes! But be aware that in 4 billion years the sun will turn into a red giant.
Anyway once a wiki post exists, it is editable by any user with at least Trust Level 1 or higher.
And is there an edit history then?
Yes! Do you see the little orange square with a pencil in it, on the upper right of this post? There you get to edit history. The edit history appears as soon as someone edited it after creation.
