What's the URL for the fantastic group theory wiki?

[Stephen Tashi]

I recall visiting a website that was a wiki for group theory and had many articles on specific groups, but I don't find it today doing a simple-simon search on keywords like "group theory". Anyone know the website that I'm talking about?

Searching for "group theory wiki" gives at least two hits on the first page - http://groupprops.subwiki.org/wiki/Main_Page plus http://www.proofwiki.org/wiki/Category:Group_Theory (plus more on the next pages).

That's the one I remembered. Thank you.
