Kill the Spare
Um, sorry. I thought I had a subscription to this thread, and I missed this post.
The best policy, if you're picky about what you take, is to look around in Beta Wanted for things that sound like something you'd like to do. You can, of course, offer your services to authors whose work you would like to assist, but if they say no, then leave it at that.
Just as a reminder, folks, anyone can answer questions in this thread. Feel free to help each other.
