I probably only missed that the question would only be put online after being reviewed. I closed the window pretty fast.
I can’t check this, because the system seems not to show so far unreviewed questions in my profile.
All posts from new members go into a moderation queue and will be approved some time later if not Spam, double post or cross post. Moderation of new members is unfortunate but necessary to stop spam, most notably the notorious B.A.M.W.A.R. spamrun that plagued the forum for weeks until moderation was introduced. New members will automatically upgrade to a full membership after a fixed number of approved posts. Sorry for any inconvenience.
