Adding members to your ignore list
Is the only current way to add someone to your ignore list is by selecting Ignored Users from your profile dropdown menu and then manually adding their name?
I seem to recall a shortcut (in the previous version of the boards) via simply clicking on their name on the post/thread that made the decision to ignore for me and then 'ignore' would be an immediate option.
It just pains me to have to acknowledge the offending person one last time by typing out their screen name in its entirety.
Try hovering over their avatar next to a post. You may see a pop-up. At the bottom, there are options for Message, Ignore User and Find Content. If you click the middle one, you'll get a confirmation page. That might be a faster way of getting them on the list.
