My apologies. It's explained several times during the registration and first post process that new users are subject to a moderation queue before their posts appear.
If your previous posts were not "approved" it might be because they appeared to lack substance, were off topic, or seemed like spam.
Again, sorry if we've made a mistake. What userid were you using to post?
Edit: Never mind that question; it appears you were using the same name and were "banned" on October 26.
Anyway, please go ahead and post your VNC-related questions or comments. Thanks...
