We run a modified version of the ioUrbanTerror dedicated server, the changes include:

• rambetter's exploit fixes
• increased maximum slot count
• decreased rcon timing (hardcoded)
• kick messages

Interested in opening more slotz, the need of protection from exploits and massive b3 lags without rcon timing adjustments have lead us to running a custom build of ioUrTded, kick messages (with suffixes) came later.

To keep backward compatibility kicking without reasons is still possible, the suffix is stored in server variables (sv_kicksuffix1, sv_kicksuffix2, sv_kicksuffix3, sv_kicksuffix4), each representing one line of text.
