Has anyone used Webissues web collaboration software?

I got it installed in about 5 minutes and the interface looks pretty cool, however I used the old version so not sure how the alpha version looks. However, this is the first time I came across software like this so wanted to know if anyone had any comments about using something like this long term in relation to reliability and security.

Also if anyone else knows any alternatives I would like to know as I am trying to figure out free solutions to build upon.
