Heh. Thanks for the plug. Now here's an amusing incident to reward you :)
Shortly after my course went up, one of the registered users (who shall remain nameless) gave my course a rating of one. I was curious, so I did some poking around and managed to actually determine who this individual was and I sent them an email asking what they didn't like about the course and what I could do to improve it. What I did not mention was that they were involved in a "competing" resource and appeared to be downvoting everyone else. This violates the following request on the site: Do not vote for your own resource or a competitor's.
Resources can be delisted if voting abuse is detected, so this person apparently became nervous and quickly changed his vote from a one to a ten, claiming "it was a mistake". Then, this person with a very unusual user name asked how I tracked him down. Apparently, he did not truly appreciate the power of Google.
