Hey bowser,
This is a common occurrence. Don't let it bother you, your post will more that likely show up in a day or two. I think there must be a 'program' that sends posts to moderation. It is just a built in protection thing to avoid 'trolls' posting unsavory things here.
I know your post was not unsavory, it is simply one of the 'characteristics' of these forums. Don't get frustrated, don't go away. We only have one moderator, and he has his hands full trying to watch out for everyone. It happens to us all, even the most senior members at times. Be cool, it will be fine.
Hang tough,
Steve
