I am in a PBEM game with 4 other guys on
http://seiv.admiral.com where we have gone through 44 turns in the Last 20 days. That's over 2 turns a day average, not a "turn every 2 days."
That probably wouldn't be fast enough for some people waiting on TCP/IP, but I think its pretty damn good considering we all have jobs and live in different time zones.
In fact we'd probably be up to turn 60 by now, but the Last week or so I have been very busy with other things and have not been able to keep up my normal pace.
