Welcome to Wikiteam on Sourceforge! Do take a look at our original project on Google Code for the latest updates to the software we use.
There are thousands of wikis in the Internet. Everyday some of them are no longer publicly available and, due to lack of backups, lost forever. Many people download tons of media files (movies, music, books, etc) from the Internet, implementing a kind of distributed backup. Wikis, most of them under free licenses, disappear from time to time because nobody grabbed a copy of them. That is a shame that we would like to solve.
