I myself am a vendor on a very high traffic car enthusiast forum, and IMHO I think it's a good idea to only have one s/n as a vendor and drop the moderation duties all together out of respect for the other paying vendors. Just put your former username or something to identify your old identity down in your sig and be done with it. You can still have fun and take shots when you are a vendor, as long as your customer service and/or product can back it up..I am new here so please don't take anything I say too seriously.
