Many (most?) mods do, although it is a matter of personal preference.

I certainly do...

many mods and dani hcan be found on IM or IRC

I accept PMs only from other mods and admins. There is no reason for others to PM me -- if you have a question just post it in the appropriate board for anyone to answer.

I will typically accept PM's, unless it is about an issue not-related to the site, then I'll re-direct you to the appropriate forum. Not only will you have a better chance of sucess with a forum post than a PM, but the end result will be available for future people who may have the same issues

ppl sometimes send me pms or emails as i post my address but i think if you had a day job as well as being a fulltime mod it would be a pain in the ass

I can appreciate not wanting to be hassled by PMs, and I do realize that there are proper forums for most any topic. I recently saw a new member post her email address and tried to bring this to someones attention as this might not have been a well thought out decision. I posted a suggestion that a moderator might want to do this person a favor and remove it and suggest that they submit it in their profile, I didn't get any response, so I tried PMing the two moderators that were shown to be involved in this forum only to be told that they don't accept PMs. How would like to wake up and find a couple hundred emails trying to sell you anything from vinyl siding to sex toys because you had a brain fart and posted your email address?

if you don't get a response, that doesn't mean it isn't being read and acted upon.
PMs like that will likely be read and acted upon, but you won't get a response telling you so.
PMs asking for personal help or other favours will however be discarded.

For such situations, use the "Flag Bad Post" link which is available in every member's post.

It don't bother me.
