DBE Community Outreach on Pinterest ✍ for ONE month (30-days), we will promote your Book ■ Magazine ■ Business ■ Product throughout our Group Boards. A group is when the owner can invite collaborators to pin on their board(s). Group boards can increase your reach on Pinterest because your pins can be seen by a whole new audience: the board owner’s followers and collaborators.
