Thanks you two, yes I do have something like this, and it supports unlimited accounts that you can switch in game. So get your sales pitch out of my forums

Shasriel, just edit the file
_ProfitUI_LoginData.txt. In that file, copy the line
<Data Name="CHARACTER" password="PASSWORD" server="SERVER" username="USER"/>
for each character and replace the UPPERCASE words with the corresponding values for your toons.
