@donnacha of WordSkill - There is no switch that determines how sensitive or open Akismet wants to act. This is how I have the commenting system set up.

Before a comment appears: Comment author must have a previously approved comment
Hold a comment in the queue if it contains 5 or more links.

That's pretty much it. Not sure why your comment was held in moderation since it didn't have 5 or more links. I try to moderate comments as soon as possible but I can't moderate them in my sleep. The one that gets the most people is the fact that they need to have a previously approved comment which both of the WordUp folks didn't have.

What do you suggest I do, turn off Akismet or change those two settings regarding comments?
