Looks like these were disabled when I was starting up the blog way back when.  I must have done so to prevent spammers.  If I had a dime for every “Click here for gear pro camera cheep!” or “Ugg boots on sale here!”  I’d have at least 60 cents by now based on my registered users.  Anyway, a few of my posts ask questions and now the settings are there to allow you guys to comment back answers.   Cheers!
