If you are under "All About Games" you will not see the Glitches board.
You'll only see Hints and Help, Discussions, Casual games, Darkside, and Boomer Reviews.
Try starting at
https://www.gameboomers.com/forum/ubbthreads.php/forum_summaryand you should see everything.
EDIT --
I think I see what BrownEyedTigre was talking about now.
You probably accidentally closed the tab. When viewing all forums, select the arrow all the way on the right under TECH SUPPORT banner and it will appear.
There's a little gold triangle at the upper right side next to each of the board sections (ALL ABOUT GAMES, TECH SUPPORT, GENERAL DISCUSSION, CHALLENGE YOUR MIND, OUR ARCHIVES). You have to click the triangle to turn it other way round, and it will expand the TECH SUPPORT section.
