Guest Speakers?

Without wanting to sound stupid as im fairly new to this site and am just getting used to all the resources, but regarding guest speakers.

I see on that section there is questions to freidman and lear, which is fantastic, but i saw the dates on those posts, being a while ago now.
So how does it work?
Is there a list of upcoming guests?

Also lastly, in the search function theres is a multimedia section, how do i look through all pictures and videos on this site in one place, is that possible?

Thanks for this, as this will only enhance my ATS experience.

I don't think there have been any guest speakers in a long time, and I doubt there will be anytime soon. My guess is that the Conspiracy Masters forum will largely supplant the guest speakers forum.

Why have there been no guest speakers in 691 days?

If you aren't going to have any, why is there a section devoted to this topic?
