Here's all the public TWikis I could find by googling for URLs containing TWiki/TWikiPreferences. Only sites that let me download this page fpor analysis are included (some timed out). Note of course these are public TWikis only; nothing behind a firewall can be seen.

If you think anything is missing from this table, feel free to edit it. The initial table was script generated, but has been subsequently hacked.

See more at TWikiInstallations directory and older TWikiClones listing.

-- PeterThoeny - 11 Mar 2004

That's great, Peter! I didn't know about the installations page. I originally built the list above because I wanted to cruise among various skins, to see what people liked/were using. The plugins listing was an accidental side benefit. An interesting point about the two lists is that there are a number of sites above that I can't find on your installations list. Some of these are probably rebrandings, but some are probably installs that didn't come from twiki.org e.g copies or pirate zips.

-- CrawfordCurrie - 11 Mar 2004

FYI, some people who download TWiki list their installation in the TWikiInstallations directory; the CoreTeam does not actively add installations.

-- PeterThoeny - 12 Mar 2004

I noticed CERN has a TWiki public site "used to collaborate on web-documentation" : It's a 01 Sep 2004 Cairo with MathModePlugin.
