First I got to say, awesome job on the statistics page, and the achievements are a welcome bonus! :)
On the achievements that require 50/100/250/1000 of something before they are earned, it would be nice to have a separate progressbar on each of them that only you can see when logged in.
And would it be possible to add more achievements. Something above WatchMaster, something between 100 and 1000 edits(will help with the quality of the site), and something above "Got the power"(more voting = a future top rated list)?
And perhaps forum posts should be a part of the social points?
