Hiya! Welcome to PlaneShift :)
Your sig is fine, so no worries there. PlaneShift will always be free - and a very cool thing, that. This is a hobby project done entirely by volunteers (who have real jobs to support themselves), so there is no need to charge anyone for anything. The price community members pay is just patience, since because this is a hobby, development isn\'t as fast as it would be for commercial games. We are just at version 0.3 right now, so not even 1.0 (and not even beta, more like early alpha) so there are definitely stability issues - but every bug is looked into and fixed with the help of our testers, regular players like you :) By just hanging around and sending us a bug report whenever you see something off, you help in development.
Hope you enjoy your stay!
