Sure mate.
The invite went out to all the old KTA members. Access was never removed, you all had access to the TS2 server we used back when we were all KTA.
C4 joined us some nights, as did MP once or twice.
We moved over to the newer version of TS3 now though, so the old info on the KTA forums about TS2 wont be accurate anymore.
I'll PM you the new details, or you can grab them off of C44U2. He and MPKS both have them.
