Tricia,
New subscribers have to have their posts looked at by Ben or one of the moderators before they appear on the forum. So, if you post at a time when none of the mods are online, it may be a bit before it shows up. I can't remember right off hand right now how many posts have to be looked at before you are able to just post right to the forum without it having to be modded in. So, if you post and it doesn't appear right away, sit tight. It won't take too long since most of the time at least one of the 5 of us is here!
