Share a link to either your NaNo profile or a location on the internet where your story can be found. If someone offered to beta read for you, would you be willing to do the same for them during the subsequent editing process?
My NaNo profile is here.
Unfortunately, I can't offer my services as a beta reader right now. My novel is far from being finished, but I'm putting it away for the next two or three weeks before I go back to keep writing. I need some time to craft and study and hang out with my friends again.
