Hmmm, maybe I should write some instructions....
To get a list (favsvrs or gamespy) with more than one set of servers - just go through them all and pick the ones you want, it'll remember which ones you picked from previous pages. When you've selected every server you want (from every different set of servers - BarrysWorld/Jolt etc.) then you click create, choosing the right type of file of course
I wrote it so it would remember all the settings, so it'll remember whether you chose favsvrs.dat or gamespy.txt if you choose to do that at the beginning, it'll remember whether you wanted it to show IPs or names, and most importantly, it'll remember which servers you chose from all the previous pages
