In an effort to thwart the ever increasing threat of (and in the recent case, actual presence of) spam in the comments, Mensa has instituted a temporary blockade consisting of the need for all comments to be approved by me before they’ll appear at all. This means that you will not see your comment right away, and that you shouldn’t panic and post it multiple times because you think it didn’t go through.
There is also the capacity for me to blacklist spammers from the site entirely. Should you find yourself unjustly staring at the blacklist page, just email me from the station you are blacklisted from and I’ll clear that up.
Future refinements to this system are in the works, and your patience is appreciated. It’ll eventually get to point where I won’t have to approve each and every comment.
