I always answer PMs. Sometimes, I'll pass the buck if someone is asking for advice and I don't have the ability to answer, I'll point them in the right direction ...to another member...
I've only had to block one person who was being nasty & mean. I think that's pretty good.
Also, I know one member who doesn't have the ability to answer PMs from the device he has with him during the day. I'm techno challenged, it's all magic to me, but I think lots of folks are on small hand held devices and intend on responding when they are on their normal computer and might be delayed or forget.
