Hey NicColt
Yes if you flush through proxy80.teamanandtech.com it'll be flushed through Mika's ... but you won't be able to use the "hosts" thing to check up on things, since proxy80 are several RR proxies... if you're crackin' under your own addy that shouldn't be a problem... but for miniteam members it can be 🙁
You should be able to go through a firewall with it yes, only way to find out is to try tho' 😉
Hope it works the way you want it too ...
With love and respect your fellow TA member
