I've submitted some pre-sales tickets (and not forum posts) to vBulletin and they treated me as a s_hit! Now I became affraid of vb support even after purchase. So I decided to get reference from vb happy or unhappy clients for vb support excellency before I buy. If you are a happy or unhappy vb user, please post your comment here.
IMPORTANT: Any attempt for official vb staff answering me here as a happy client for support excellency, does not help anything. So don't try to trick!
