So I ventured somewhat tentatively into the firstclass client that came with the Applications CD Rom, running it in WINE of course. I picked up on one conversation where the OP mentioned they were on a nix system and a respondent had replied similarly. Of course I had to wade in and I'm glad I did. I pointed them in the direction of the OUUbuntu project, as sent to me on twitter by @stuartbrown of @openuniversity fame!
Then Max Ashton, of *fame yet to be determined* let me know about the FirstClass Debian Package!! Oh yes, so now my firstclass client is as pretty as a picture, this picture in fact...
So that's my tip of the day, if you're using Linux, go to the firstclass download page and grab the linux version of the client!
