to the question on the server note, before i moved i was on cable modem. go to
http://www.dslreports.com to check your UPLOAD speed. if it at least 250 you should be able to host a 8 man dedicated server just fine. just remember to take use of maxping and autokick.
to the question on leaning. it is not only a server rule, but also a clan rule. leaning around corners is fine, but leaning back and forth during a gunfight IE: biding your keys, is considered cheap and to most people is cheating. leaning like that is not allowed on either of our servers.
to the question about realism, i currently only have remove weapon mods on at the time, as i have just started MY server, i am not sure what the other server had running as far as realism. and you are more than welcome to come in and play anytime you would like.
