Wow, these are all really GREAT answers! Thank you!! I LOVE learning this kind of stuff and it's overwhelming sometimes seeing all the different stuff that's out there to learn (like the MD5_hex & MD5_base64, etc).

That said, I went with the Crypt::RC4 solution. Our magazine is free to US subscribers (it's a trade magazine for restaurant folks, so you guys wouldn't be interested, I bet ;)), so there's no credit card #'s and the folks that do use this online that receive the e-mail (or actually have e-mail to begin with!) won't monkey around with the URL to figure out others (especially when they see that awesome encryption of their userid: 62c88fb1d64d).

Thanks again for all your responses!

Jason
