It looks like my longtime comments provider, YACCS, isn't around. I'll wait a couple more days to see what the situation is before I go in and tinker/tamper with the commenting function on the template.
ETA: Looks like after seven years of service, YACCS discontinued its commenting service on Dec. 23, 2008. Wah! It was fun while it lasted. I will see about adding blogger's commenting function here.
