It isn't that you CAN'T be on both, as it is not against our rules. It isn't against our rules for you to be playing on 100+ servers all at the same time either. However, whether it has something to do with the cookies or something to do with our efforts to deter multi-accounting, something seems to be flagging out those multiple tabs as a second log-in.

If you want to try to do this, I'd suggest two different browsers. Have firefox opened for AgeI and then Chrome for AgeII or something similar. That may get you around this issue.

Again, you are not breaking any rules being logged into more than one server at a time, but you are obviously flagging the system somehow in the process right now. The easiest way to make the problem go away is to just do one server at a time.
