Well, there is still a problem with my student's blog. When we try to comment on it, he receives the comments in his email, but they don't show up on his blog. We are continuing to work on it.
He was very excited, though, to read the emailed comments that he got. This is the first time I have seen him excited about blogging. Thanks to those of you who tried to comment. I'll let you know when the problem is taken care of and your comments will show up as they should!
