I'll have to see what's available. No way I'll use the Zone though. If the JK2 server browser is identical to the Q3 one, I may consider using Qtracker or maybe GSA as a last resort.
I thought the Unreal games had the best built-in server browsers.. hopefully the JK2 team tweaked the default Q3 one just a bit.. I liked being able to sort by folders, rather than just have one giant filtered list like in Q3. ; p
Still, anything's better than installing that crappy Zone software and putting up with all the bother over there.
