If you have downloaded and tried the mod recently and have seen maps which you have not got the best thing to do is this ..
1. start etf
2. in console type the following cl_allowdownload 1
3. join a public server
4. the list of maps which you dotn have will automatically download for you.
Remember to join the server which matches your etf vesion and et patch otherwise your gfx will be screwed and you will have toreinstall i think the only server with a lower etf version than the current 1.6 has bots on and is american the ip is 64.81.110.40:27960 so don not join that one.
When you play on a public there a few unwritten rules that people should understand otherwise you will get moaned at and maybe kicked in extreme cases.
Things like no yard dm fighting between bases ETF has a rule which states that the offence of one team attacks the defence of the other and vice versa .. its beneficial to each team to have a full enemy offence vs a full defence instead of a yard war which ends in 0-0 ..
May sound a bit lame but works really well.
Any questions ...
