After all but forgetting about this site for months, I've come back and found a ridiculous number of spam accounts (and a few actual spam comments). So I have cleared out the comments and accounts. If you created a real-person account and I deleted that by mistake, I apologize, and please feel free to create a new one. I will be clearing out accounts periodically if they look like spam accounts. If you create an account and want to keep it, please post a coherent comment. I will approve comments and accounts from what look like real users. 8^)
