reply does not show up..?

Hello :)

I have just replied to a thread "Identifying phone types" in the forum "Nokia general - FAQ" but my reply does not show up?

I did it already last friday, with the reply not showing, so i tried again today with the same result. I could write the reply, attach the file, click "post reply" but then it transported me back to the main forum view. When i tried to do it again (using the back buttons in my browser) a message came up, that my reply is a "duplicate" and also when i try to get there via my profile, it shows my reply as "last post" but still, trying to go there doies not show my reply.

Kind regards...
