First of all: O-M-G THANK YOU SO MUCH 
I’m astonished at the level of the response, my only consolation at seeing such amount work is that is a given that this is going to be of great help for many. This opens a lot of new possibilities, all in benefit of the development of a forum as a hub for a community.
Second: I’m so sorry for answering so late since you answered so quickly. I was first unable to get to my computer sooner, and second I only wanted to answer once indeed I had gone trough the code you so kindly commented (line by line 
, my goodness, thank you so much). Of course, everything worked perfectly, the entire feed loads so quickly… I’m in debt 
Thank you again Johan, I really hope to be able to contribute from my part with my own experience
PD: I’m totally keeping the heart for the static preview.
