Here are some pretty simple rules.
Post price, location, payment and shipping options, and don't forget - pictures are not required, but will greatly help your sale. Please don't post a ton of items for sale in the same thread, unless you're parting a bike out or similar.
Posting "Or best offer" is fine, but not "Make an offer". That's for eBay.
Don't post links to eBay, Craigslist or other sites. The post here makes it for sale here.
Bump your thread once per week.
Only post a reply if you want the item. Relevant questions acceptable. Any negative comments will result in a ban. No BSing in the thread.
Early bumping is becoming a problem. Once every seven days, no earlier.
Also, comments like, "Nice bike!", "That's a great price!" or "Good luck on your sale!" are not needed. If you want to tell the seller those things then send a PM to them.
Only post a reply to a thread if you have a question about the bike or parts or if you are interested in buying the item/items.
Once an item is sold do not post any more comments to the thread.
Thanks!
