Here is the guideline for reposting:
REPOSTING: Rental Posts to the Housing/Offices category and Services/Referrals Wanted posts (when you want to hire somebody) may be reposted weekly. Events may be reposted after 7 days if the event is less than 7 days away. All other posts may be reposted after 14 days. This applies across all categories (You may not repost to a different category any sooner).
When your post is eligible to be reposted, you will see a Re-post button at the bottom of your post when viewing your post on the website:
This button will send your post back up to the top of list and send it out in the Daily Digest. Your post will remain active on the website for at least 30 days.
If there has been a public reply, you will not be able to repost using the repost button. Instead you can copy your original post and create a new thread and then paste it in.
You are welcome to edit and save your post before using the Re-post button.
