2 days before, i.e. Monday (2 Apr) I tried to post a thread on Canon sales forum at 5AM+. After clicking the submit button, the new thread did not appear in the forum or in my recent posts. Believing this to be an error, I tried again to no avail.
However, my post on other forums turned up fine, i.e. it was posted the moment I hit submit and appeared in my recent posts.
I had informed one of the moderators, sebastiansong about the problem I encountered but have not receive any reply from him.
