Without getting into administrative issues here

How long is an appropriate amount of time to wait before putting someone on ignore here? I mean, after trying to work things out in PMs... because I've been erroneously accused of sending someone a PM and then putting them on ignore "so they can't respond." It wasn't that way at all.. so now, if I want to just not read someone.. and have PMd with them first.... how long do I wait so I won't get into trouble.
Take into account (like most here) I might forget I wanted to spare myself from reading this member... and if I don't do it while I'm onsite now... sigh. Do you think you have to always notify them you are putting them on ignore? I don't. I mean, Idon't think you should have to tell them.. that could also be implied as flaming, couldn't it? And what if it's just the mood your in, and you will take them off ignore later.. if you told them, then you might lose that relationship, right?
Why do I even care!
