How do I delete my Steam account...?

to delete your steam account, you should do this :

Uninstall Steam, delete the Steam directory, then delete the stuff in the registry.

To get into the registry, hit Start->Run, type 'regedit' (without quotes), and hit OK.

Navigate to HKEY_CURRENT_USER->SOFTWARE->Valve, and just delete the entire Valve folder, there's nothing there you really need

you **** off
