create a new email account.  many sites allow you to easily create a new, free email account, which you can use to create a second FOD account.  and for subscribing, you can use the same email to subscribe two accounts (since they require a non-free email to be used to subscribe).  i've got 3 accounts i use in larkinor, and two of them are subscribed.  i created them with 3 different emails, but subscribed both of the subscribed ones with my university email account.

As said before, just make a new email address and create a new name.

Durhh, i meant to say you can use a free email account, like hotmail, when subscribing...
