So what is going on here? Tried posting a comment on the latest Unprofessional friday and I get that message?

I made a post here about it as well. According to the staff who posted there, it's on a two-hour timer to prevent spam comments. If you've got a lot of tabs open or are watching a very long video, you'll need to refresh to post. It would be nice for it to be on some sort of visible timer so you didn't have to figure out after clicking submit.
