When can I repost on the for sale forum?

Good question, but there are people who repost everyday.

I think you can post once a day. You can hit the take action button to delete your old post.

THE RULES:

• THIS IS NOT AN AUCTION SITE.
  YOU MUST POST THE PRICE(S) OF YOUR ITEM(S).
• This FOR SALE forum is for private individuals ONLY.
  This forum may not be used by hobby dealers, forum sponsors or other commercial entities.
• You can post ONE NEW THREAD PER DAY.
  Multiple posts by the same person on the same day will be deleted.
• If you are selling multiple items, put them in a SINGLE THREAD.
• If you don't like the seller's price, keep it to yourself. A seller can ASK any price he wishes. If the price is too high, the items won't sell.
• Do not attempt to keep your item on page one by "bumping" it to the top.
  Threads where "bumping" has occurred will be deleted.
• If you send an email to the seller, DO NOT post "Email Sent!" in the thread.
  That is considered a bump and it will be deleted anyway.
• Do not use this forum to post links to items that you are selling on other venues such as auction sites.
  (Yes, this means eBay.)

Yes, please delete the old post!!!

To me that would be the same as Bumping. I know there is no rule but I would think you could list an item over again after a week or something like that. I have wonder about this same thing in the past thou. 

I let if go over a week on unsold items.  I always delete the earlier post.
