PC version is great, any advice on how to get my second account on battle.net? maybe someting similar to wow where battle.net has an account drop down menu?

=EDIT=
Ok, i managed to get two copies running, Two instances of battle.net running side by side (different emails/account),
Duplicate game folders (two installs).
Tricky part was telling battle.net which folder to use, changing in one battle/net client changes it for both (frustrating), if i’m quick enough i can load one, change the settings and then launch the second.
