If you are getting pinch hits by email, reply to the email that has the pinch hit you want in it, and include your ao3 name.
If you're viewing the google group forum on a mobile device, you can claim a pinch hit by emailing
yuleti...@gmail.com with your AO3 name and the number of the pinch hit you want to claim.
If you're viewing the google group forum through the desktop version, you can use the same method as mobile, or scroll the welcome post above the topics to see further options.
If you successfully claim the pinch hit, we will reply and confirm that it's yours, and assign the recipient to you on AO3. If you don't hear from us, it went to someone else.
What does it mean to pinch hit? Are there penalties? Are there perks?
