I’ve made a little wiki with information about land in the Second Life virtual world.
It’s called Land Answers for Second Life and it’s at http://land-answers.wiki.zoho.com .
So far it consists of material from the Second Life Knowledge Base, only it’s in an editable location. The permission are set to publicly editable. You can add comments as well as edit the body of the text.
The editor uses a WYSIWYG mode, much simpler for many people to use than an editor like the one in wiki.secondlife.com.
If you generally use the Opera browser, like I do, you’ll want to switch to Firefox or IE while editing the site.
As I said, at present it has info from the SLKB, but – it won’t time out on you.
