I like high-tech themed email addresses.
Too bad you have to pay for those star trek accounts. And I wonder if they are really legit; perhaps one day the holders of the Star Trek trademark will come after them for unlicensed use or something.
If you are interested in a high-tech themed email address, BOINC Synergy offers accounts: e.g. - email@example.com
BOINC is the group that oversees the SETI@home project, which scans for signals from extra-terrestrial life, among other projects.
The email service is powered by Gmail.
There is also rocketscientists.ca, which is powered by another third-party service.
And there are several more.
