Guild Wars 2

With the sale on I bought another account and was wondering about the best way to set things up.

I like that it remembers your username and password but when I tried copying my existing GW2 folder to GW2a, running gw2.exe from GW2 picked up the username and password of my second account after I launched GW2 from folder GW2a. Is there any way to have one version that remembers account 1 and another that remembers account 2?

I don’t have any plans to run two instances of gw2 at once but is this easily done?

ok found the answer in the wiki with the command line options
