It's very cool, that there is the Sandcrawler Server.
But there is one problem:
It's (very) often empty, and if there are 2 guys playing it's not that good (CTF), in TD it would be ok.
My suggestion is to make 3 server (If possible)
- 1 With the CTF Maps
- 1 With all Maps for TD
and 1 with the normal maps (Garden, Depot etc.) to advertise for this page to get more people to the forum and downloading maps.
