"Customization" should have a description that it's about Jlink, Toolkit, etc. rather than custom installs, configuration, templates & drawing formats and things like that. That would go under "System administration".
The Creo Parametric Tips section should make it clear that these are tips from PTC staff rather than a place to share tips. At least that's what I assume it is since posting new topics seems to be disabled.
Hello Doug and sorry it took so long to get back to this !
Navigating to the main category (for example in Creo , when being in this page: https://community.ptc.com/t5/Creo-Parametric/ct-p/creoparametric ) you see the names of the boards + a description. However, you are fully right that some boards (like Tips) do not have a description. So we have taken the point to work on describing those boards for easier consumption. Many thanks for the suggestion !
(attaching an image to illustrate the description of one board that has it).
