How often can i repost?
The reposting limits often vary from group to group and the limits are usually different for Offers and Requests. Most groups allow Offers to be reposted after one to seven days and Requests after 2 weeks. The time period will often increase if a post has already been reposted a few times. For example, you may have to wait a month or more to repost a Request that has already been reposted a couple times.
To learn more about the reposting limits, you can contact the moderators.
