It’s the QResearch threads in that catalog or index you would be looking for. They are fast moving and get filled quickly, because each thread can only hold (i think) 751 posts.
I am not unskilled with computers, yet I would hesitate to post there without being armed with a number of good security tools and a solid VPN.
Attract the wrong kind of attention there from any side, and personal consequences could be quite steep.
There are some very nasty wolves among the sheepdogs there.
How do you get to the Q research threads? In the past I clicked on the number at the top of a Q post. There have been no numbers in the past 4 or 5 posts. Am I missing something?
