Comments not working on my askbot.com site
I have two sites hosted by askbot.com: http://mcmcclur.askbot.com and http://calc3.askbot.com. The second one was set up very recently as a discussion forum for my Summer calculus 3 class. For some reason, I am unable to leave comments on that new site, though I have always been able to do so on the first site and still can. I've fiddled with all the settings and manually increased my Karma but nothing seems to work. Any ideas?
