When you signed up is irrelevant since what counts is when your account was actually approved. I can't see approval time, but considering your name is still on the list of members who joined within the past 24 hours (clicky), it's a safe bet that it has not been a full 24 hours quite yet.
Then the problem is with your e-mail. I assume you already followed the steps posted in the sticky thread on that topic, and checked spam folders and spam settings? You may also want to be sure your e-mail provider is not blocking e-mails from SWC.
The e-mail Phryss mentioned is assistants@swc (note spelling), but that was in case you couldn't get registered with your e-mail address, which you apparently did. Do you need the e-mail address changed?
If you had gotten it wrong, you would have received an error message at the Lost Password screen, rather than confirmation that it was resent. Unfortunately there is nothing else that we can do about it, short of changing the e-mail address to a different one for you. It is most likely not arriving either due to your personal spam settings, or due to your e-mail provider's settings. In the first case you should be able to fix it yourself by checking your e-mail program's settings, and in the second you would need to contact your provider directly.
If you do want your e-mail changed, you can post or e-mail (firstname.lastname@example.org) your handle, old e-mail, and the new e-mail address, bearing in mind that it still must be a non-free e-mail account until you have logged in for the first time. If you have a friend who would be willing to let you use theirs and forward you the e-mail, that would work, too.
Internet Service Providers usually offer their users an e-mail address to use, and as previously mentioned, we do accept those. Chances are you have a friend with access to an ISP e-mail address. We also accept school, work, and personal domain (admin/webmaster account) e-mail addresses.
