Where do I find betareaders? There are several ways to go on this one.
- Social Media: I simply tweeted and posted that I needed betareaders (and betareviewers) for my new work and was anyone interested? I told people I needed their email and to DM or PM me. I heard from about thirty people over the course of the month prior to release.
- Groups: If you’re in any Goodreads groups, LinkedIn, or Facebook groups, you can draw on these folks to see if anyone would be interested.
