A pet peeve of mine is when I get an email regarding a post I created or marked "watch," the email states that it has been responded to. I go to the topic only to find a one word response. Some days I could get 20+ of these, because someone is going back through older posts. It then takes 30+ minutes of my time to go and check these to see if someone had a question about my topic, or has added additional info into some one else's. I have been marking "watch" to some posts for 3 years, so there are a lot of them out there. Commenting "very pretty" Or "nice quilt" or "thank you for this information" is one thing... but the other one word responses really were not necessary, did not add anything to the topic and go against the board's rules.
I finally had to disabled the email notification function to unclog my inbox, and I know I am missing out answering questions on my own topics, or learning more from other members.
