I used to play tons of D2, but havent for quite some time. i never remember there being any "beta realms" though. can someone tell me what exactly they are?

beta realm has been around for a few months. players joined this realm to test out the upcoming patch and give feedback on what they though.

Server will be reset soon and no more PTR (i can say this as a fact).

Oh yea... i havent played in a couple years (i must really be a loser to still be here) but can anyone play the beta realm or do you have to be someone special?
