So you want to check and see what name you're folding under?
if so, go to the f@h directory and open client.cfg with notepad, or something similar. The first line will tell you what name you are using.
in mine it shows "[settings] email=hooziewhatsit......."
if you want to change it, either change it in the file, or delete the file and start f@h again.
hope this helps
