I usually don't use Read Receipts for message boards. But, I know how it feels to wonder if someone has read an email. Especially if I email a school instructor, where he/she has the power over my grade. I've also emailed my psychotherapist and wondered if she has read an email or not. I'll worry about it for no reason. It really sucks.

I think the worry is about caring about stuff. Sometimes we care too much about the opinion of others. Sometimes we think our opinion is more important than it really is. (A great example of that is evident in BLOGGING and commenting to others' blogs. I could blog about this point.)

It's best to balance things. I don't know how to do it myself but consider changing behavior occasionally and you'll get different results.
