I do not use the two modules any longer, because my UHK v2 is now solely used as a compact (non-split) keyboard.
Both modules are barely used. The keycluster has silent tactile switches (Kailh Ocean Whale). When someone needs the keycluster and trackpoint module send me a PM.
That makes sense to try to keep the forum valuable. On the other side being able to sell or buy UHK related items is also useful for the forum members – which we cannot find at another place. Simply because the forum is the meeting point for UHK users.
One solution would be to create a category. This is for example also how Keyboardio does it and that works great – without disrupting other discussions. Maybe you can consider that option.
I understand Laszlo’s wish not to clutter up the general feed. On the other side it is dependent on the person. Some will want to see trade related posts, others won’t and some will not care.
Suppressing those posts from the news overview could be a good compromise indeed.
