Just a warning: lately, there've been a lot of nasty, slagging, one-off comments coming in from Yahoo accounts — you know them, the usual unreadable smear of a name that we all call yahoomess. I'm considering cutting them off altogether. All it will take is one click and the yahoomesses will no longer be afflicting the site.
If there is anyone who objects, speak now. If there are a significant number of reasonable people who are logging in with those IDs, and have managed to successfully generate a readable name for themselves, I'll reconsider.
