If at first you can't find a thread - call it censorship! Sounds good but is factually incorrect.
When a thread is considered by a Mod to belong in another forum then it is moved and the Mod has an option as to how long to leave a 'Moved' marker. Normally it is up to 24 hours but such notices clutter up the page.
one has to trawl various forums
No you don't - there is an excellent (and under used) Search facility! May I respectfully suggest that you use that?
