Hello @x_nerve,
thank you for reaching out to us and bringing this up.
the forum cannot be searched without registration.
We had a quick internal discussion, and we agree, guests should be able to search the content of the forum. I have changed the settings; you can now also search as a guest for topics. Searching for users and creating topics intentionally remains disabled for guests.
"Maxon One" has fully promoted the subscription system, but Plugin Cafe forum and Redshift forum accounts cannot log in to each other.
I am not sure if I do understand what you mean with 'log into each other', but I assume you are talking about having automatically provided user accounts via your id.maxon.net account with which you also identify with the Maxon products you have licensed.
This is first of all technically not trivial, but it would also lock out anyone who does not have a Maxon ID account. To be able to search over all forums, the forums would have to be integrated into one database or we would have to substantially modify the frontend (NodeBB in case of Plugin Café). In the close future there are no plans to do this. In the long term Maxon has some community management plans which might address the integration of multiple forums, but I can give neither a guarantee that this will happen nor an ETA. If such a system will be built, we will likely also use Maxon ID for authentication there.
Cheers,
Ferdinand
