There are numerous author groups which have a variety of excellent benefits. These are where you can find authors with whom you can do a beta swap or provide editorial reviews. There may be one in your local area where you can get together face-to-face with other authors. If not, there are several options online. One place to start is Linked-In, which has several author groups. Facebook has some as well. Make sure that any other groups of which you are a member, even if they don’t relate to writing, know that you are an author.
