I decided to sit down and get my materials in order. Mostly this consisted of adding a UID for my job at OSAF to the key. I ran gpg and successfully added a UID. Then I tried to send it up to the MIT keyserver. I switched from using PGP to using GnuPG when I discovered that there were Windows binaries that could also be used from Thunderbird's EnigMail plugin. The send-keys operation reported that it had successfuly transmitted my key, but when I queried the MIT server about myself, it didn't show the new UID.

After many minutes of futzing an googling, I discovered that some keyservers have problems with subkeys. Apparently the MIT server is one of them. In order to get subkeys to work, you need to access a keyserver that is running the SKS keyserver codebase. I changed my keyserver setting in GnuPG to use hkp://keyserver.bu.edu, and the new UID appeared. The UID also appeared at MIT, so now that works as well.

If you're getting ready for the party, you probably want to know this.
