I have looked back through your posts to see why one went into moderation. It was because it contained a link.
Posts from new members containing a link go into moderation automatically as a precaution against trolls and spammers. Once you have submitted a few posts, any containing links will appear automatically, without being moderated.
As Tdol said, a moderator will normally approve moderated posts fairly quickly. It can happen that we miss one occasionally. If you have submitted a post that has not appeared after twelve hours, you can ask about this in the
Support Area. This will bring it to our attention.
