A general FYI as a placeholder until I post something more meaningful...
1. I don't mind "Thank-you" notes for s, llamas, comments, etc. While it occasionally results in a large pile in my inbox, I would rather have confirmation that there are still people on the planet who believe in good manners and make an effort to practice them.
2. Having said that, I understand if someone else doesn't want to see "Thank-you" notes for faves or whatnot, and I do try to pay attention when I visit others' profiles to thank them for things. If I catch your notice that you don't want to be thanked, I do respect it.
3. Having said that, I will occasionally miss such a posting if you clutter your profile with ginormous screencaps and acres of stamps. Please keep in mind that if there's something you want me to see on your profile, you must prioritize and compose accordingly.
