Lately, I've been working on the grammar group book. It's going to be sort of like the Postsecret book, but with the best grammatical pictures from the Facebook group. The problem is that I have to get permission from every person whose picture we want to use, and people have been surprisingly reluctant to give that permission.
Some people have asked to be paid, which is not unreasonable, but my publisher has ruled that out (and I certainly can't afford it). I've sent more than 2,000 messages to people on Facebook soliciting permission to use their pictures, and fewer than 200 have responded. Some of the 200 pictures are too blurry or too small to use, or they're just not funny enough. Facebook has a limit of around 100 messages that you can send per day, and I've maxed it out almost every day for the last month.
My readers constantly surprise me with their ingenuity, so here's my question for you guys: what approach would you take for this? I can continue to send messages, which is time consuming and hasn't been very successful so far. I also posted a message on the Facebook group's main page, and have mentioned it several times on this blog. Any other ideas?
