Beta post.

[mirrored_illusions]

Here are a few communities where you can look for someone to beta read your story. :)

sg1betas  - beta_search - find_me_a_beta  - willbetaforfood  - sga_beta  - betabetabeta  - betacommentary  -  thebetacorner 

Not all of them have been active in 2013, but it's a place to start.

Fanfiction.net has a beta section here.

You can also comment on this post if you need a beta, or if you want to offer your services.
