I have been reading a couple of articles and can't seem to post a comment on any of them. I've tried on multiple articles, as well as different computers and web browsers (Internet Explorer and Firefox) to no avail. Help please, the world is being deprived of my wistful banter! :-(
I looked to see if you have any bans from the comment section so it is probably some glitch or problem with your account. If the problem persists you can send the moderators a pm though. Oh and since you're new you could try making a new account and try commenting with that.
