So revisiting this....
I am now renting a 150 slot Mumble server instead.
Ts server is good till december I think, then I'll stop paying for that. (Costs more to rent the mumble server, but handy for Ganked nights I run in eve that see 100 pilots at times and other random eve stuff)
Reasons: Better quality on mumble, cheaper for larger numbers of people to be on a server (ie the £20 I pay a quarter for 150 guys on mumble would only get us 16/18 people on TS...), no passwords required (you use a certificate instead and register with the server to preserve your name) so no chance of ebil hax etc, generally its like the good stuff of TS minus the quality issues.
