What about timers? Just like how users must wait for a specific amount of time before posting his/her 2nd post.

I suggest for BUMPs in Garage Sales we implement a 60 secs rule. That way:
- the seller/buyer will need to prioritize his/her thread (for BUMPs) and at the same time,
- it'll help control them creating multiple threads (might as well cramp relevant things inside one single thread instead of creating multiple unnecessary threads cuz they can only BUMP one thread per minute).

Pardon my broken English.

i still prefer merge into few threads... at least the thread based on brand such as Proton Body Kit, Perodua Body Kit , Toyota Body Kit , Kia Body Kit, Honda Body Kit, etc
if Wira Body Kit, Waja Body Kit, Savvy Body Kit, Tiara Body Kit, Juara Body Kit, Gen2 Body Kit, Saga Body Kit, Perdana Body Kit, Arena Body Kit... (wei, still haven't include other car brand's models into...)    

otherwise create another sub sub-forum under "Automotive Garage" named "Body Kit Garage"...

good example such as moderno thread... all the bulk order graphic card in a thread only... look informative and neat...
