Thank you for the ego food.

As you might imagine, coin collectors can be a somewhat reticent lot. I'm not sure what kind of patronage we'd get from some sort of bio page. Another consideration is that Internet communities rely to a great extent on relative anonymity to protect their members, and we are
very efficiently indexed by Google. So publishing biographical details here would be the equivalent of shouting them out loud to a crowd; many posts on this forum can be found in a Google Search less than 5 minutes later.
Now, for some tools to satisfy your curiosity. First, when you're logged in you can click on the Members icon above (the group of people) and list us all by postcount, membership date or whatever you like. That will give you an idea who's been here longest and who talks the most (

). It also allows you to cyberstalk individual members' posts if that's what works for you.

Also, note that your Profile has a "Bio" area - you can click on anyone's username and see what they've chosen to say to describe themselves. This is, I fear, a feature which gets very little use. I haven't used it myself.
But given our mission to develop and nurture new collectors, personal privacy is very important to us. And since everyone besides Moderators and Admins are private parties in no way beholden to us or affiliated with the site, any information released would have to be purely voluntary on their part.
