UPDATE!! The Ignore feature
Update--your profile now has a list showing who you have ignored, and you can reverse that action! Thank you, Jim!
Forgive me if there's a better place to post this (and then let me know!) -- are there any planned changes to that feature at this time?
As I understand it, when I ignore another user, that can effectively block an entire section of a thread which they've posted in, not just their responses. So if someone is posting in a way that I don't want to see (but isn't violating anything enough to warrant a ban), and they happen to be in nearly every thread/forum I go to...to ignore them would effectively cut off the site for me.
I'd just try it out to see what happens, but I don't think at this time we can reverse putting someone on ignore.
