Sorry Jennifer but i have to agree with BUBA.

First you will find the best AAA Player there, much better in the mean , then the club only players like in the DAAK or elswhere.

Secound , sync probs are very rare but even if a game chrashes , you have an Autosave. I sometimes  watch tv on my Pc or listen to the radio on my pc  beside my games and i never had any big issues with triplea.

Third , of course you can let your firewall be active, triplea works good with hard and software firewalls, just forward port 3300 (or any port other you wanna use) and you will be fine .
