I've beta-ed before for my friends, as well as for many authors on this site. I'm mostly here for spelling/grammar support, but if you want an opinion and more feedback on your fic, then all you have to do is ask. If you really need to bounce ideas off of someone, I wouldn't mind exchanging messenger screen names if you want to talk in real time. I'm not incredibly harsh (or at least I don't intend to be) with my critique. The easiest way to figure out if you want me to beta is to read one of my fics. That way you can determine if I'm skilled enough, and if you like my writing style.

When you send a PM, please say something along the lines of "Beta Request" in the title. In the actual message, I would prefer if you gave a quick rundown of the story; series, main pairing, side pairings (if applicable), maybe a quick two sentence summary, and the length. If you haven't finished the story, then please give me a rough estimate on the length, especially if it's a multi-chapter fic and/or if it runs over 10,000. And please let me know if the story is complete or in progress.
Update (2/19/19): It has come to my attention that the mobile app has a PM system that is separate from the website. (As in PMs made from app or website aren't available on both platforms.) I rarely use and check the app, so I apologize to those that have messaged me and have never received a reply. If you were one of those people, please feel free to message me again. A lot of those messages are old enough that I don't feel comfortable replying. However, I will still be using the website as my main platform.
