Perhaps creating an index or table of contents page containing links to tutorials would help new comers especially if it were a sticky.
examples
Update guide............. Ubuntu Mate Update Guide - #12 by lejacobs
Linux Security............. Security on Linux and do I need an AntiVirus app? - #4 by maro
Screen Blanking aid.. Stop the screen from blanking in Ubuntu - #12 by wolfman
I didn't try to organize - I just scrolled to the first 3 on the list you created. If this is adopted I'm hoping that anyone creating an entry for Tips, Tricks, and Tutorials would be able to update. Having an unordered TOC or index might prove more useful that searching the entire section.
