I have made a minor change with regards to letting people post comments to discussion entries. It used to be the case that anyone was able to post comments on the site. Unfortunately that meant that I got spammed quite badly. I realized that I had a huge approval queue for comments. I went through some of them and published them. Sorry if I deleted a comment of yours. Please repost if your comment got lost.
From now on, new comments can only be posted when logged in. Sorry for the inconvenience, but this should help a lot to make discussions more interactive through the comments.
Thanks for everybody that commented on broken links and such. I hope I fixed everything at this point. As always, if you have any input for the site, please let me know. Either by sending me an email or posting something here. Thx!
