Not really, but since there happens to be little alternative in this case, as of yet...
Even typing them in as "John DOT Doe AT Server.com" would be better IMO, but then again it is more work for the moderators, too...
Also may I suggest the following: A thread is made which is closed and it will be titled "HOI2 beta-test announcer" or something, and then all these people could subscribe there, and when the Beta starts one of the mods could open it and post "It has begun". All ho subscribed get the info, just like here.
Then we would all get to know it without this thread. Less work for the mods and no SPAM possibility.
