How long do posts typically take to be approved?

I understand that new users have to have their posts approved to cut down on spam, but I’m curious how long the process typically takes? I posted a question to the forums about 2 hours ago and my post still has not appeared on the site yet.
I don’t mean to come off as impatient,it takes as long as it takes, but if the expected wait is scaled in days rather than hours I will at least stop checking back here today, haha;)

Hi- I’m also waiting for a post I made to be approved (in the particle/dynamics section). It might take over a day. Not sure.

Most of the time, posts by new members to the forum don’t take more than 24 hours to work their way through the moderation queue.
