By looking at publically-accessible databases, I am able to determine the names and addresses of all those who have posted their callsigns here.
Duh.
Anyone who registers as a HAM knows (or reasonably should know) that their callsign is personally-identifiable information. Reporting this thread to the mods (who may not know anything about amateur radio and thus not aware of the obviousness of your claim) is disingenuous. If anyone who's shared their callsign here has a problem, they are more than able to contact the mods or edit their post themselves.
As for the topic at hand - I took the test for Technician last summer at a hacker conference and failed because I had been up for 72 hours straight and wasn't doing basic multiplication correctly. I'm looking forward to eventually finding the time to go for my license again.
