There can only be one reason Narf is using an alternate name.. He forgot his password for the old one. Because you can access your login from any computer anywhere. you just need to type in your name and password. The fact that his comp broke down and died (very sad) has no bearing on the shrapnel forums.
Narf, if you forgot your password, why not contact Shrapnel? And don't they have an automated password retrieval where it gets sent to the e-mail addy they have on file for you?
Anyway, I hope you get your old login back narf, Cheers!
