I'd appreciate some help testing a site I built this weekend.

/]b1t[Suspicious link removed] lets you receive email address at your Bitcoin address. For example, if you control 1ABCdefghijklmnopqrstuvwxyz, then you can read the mail at the inbox 1ABCdefghijklmnopqrstuvwxyz@b1t[Suspicious link removed] (and, of course, anyone can send to that address). I extended bitcoin-ruby to add compact-signature key recovery, which both lets you prove ownership of a given Bitcoin address and replaces username/password sign-in completely on the site.

The use case I was mainly thinking of was something like Mailinator, but where you would know that you and only you could read mail at a given address. If the site catches on, however, it could become a de facto place to ping someone whose public Bitcoin address you know.

The site is new and not well-tested. Some of the caveats:

• As with all webmail, you must trust the operator of the site not to read your mail. You don't trust me, so please don't send critical or sensitive email to any address.
• Along the same theme, the site is an experiment and I might shut it down. So for now, don't rely on these email addresses existing for any period of time.
• It's hosted on Heroku with the developer plan. There isn't much storage space, so it'll be pretty easy for the system to be overloaded. Send an attachment of any size and you'll kill the site. Again, don't trust this site with mission-critical email.
• I am very interested in feedback on the sign-in process. I'd like to learn whether Bitcoin signatures could become a viable substitute for username/password-based sign-in flow.
• Finally, to repeat the warning above: please don't trust that this site is in any way secure. The site surely has bugs that might enable others to abuse the site. I'll try to fix those bugs as I learn about them, but at the moment the site isn't well-tested.

Thanks in advance!
