I have been using 30gigs service while it was in BETA for a little while now.While logging in today I say this:
Registration is open to anyone until 1/31/2006. Get an account today!.
When I first had the account, they had stated that in addition to email, they were working on a way for users to utilize the 30 gigs to also store files and such. I am not sure if that is still the roadmap for the service, but in the meantime, it doesn’t hurt to sign up for an account.
