If you need a beta, feel free to contact me. Credentials mean very little online, so if you want, send me a short piece sprinkled with grammar/spelling mistakes amd I'll correct it.
When I read anything (esp. online), I look for: spelling/grammar, plot, text spacing, pacing, realistic dialogue/interaction, character development and if fantasy/sci-fi, world building.
Yes, it's also possible for me to miss things too.
