I posted on twice on the symptom board, but my post does not appear?

I saw your post -- Under Pre-Diagnosis, Testing & Symtoms. Someone has already posted about it.

From what I have seen... New posts show up in the View New Posts section you will see this next to "My Controls"
When you go into the section you posted sometimes they are at the end till someone posts (not positive about this part but have seen mine do this).

You posted late last night, when most moderators are sleeping. Your topics posted, but will be at the very end of the forum until a moderator reads it, approves it and pins it. At which point it goes to the front.

I have just pinned your original post, and set the second (duplicate one) to invisible for Scott (admin) to delete.

The reason we do it this way is, that we like to weed out spam, foul language and other inappropriate posts/content right away to keep this board a place we can all be happy with.
