The core benefit I see with a gaming community having a system specs in the “Signature” can be beneficial for ppl with support questions. I know with admining a couple of VR Communities when a person is having problems with a game/device. Quite often need to request them to post these details.
That being said you can install signatures and keep it pretty clean with Hide Details. Or even add a toggle say in the sidebar, header to turn on/off visibility. Or something completely different. Like a computer icon in posts near the poster’s avatar that can be clicked to pull up a pop up window. The flexibility is very wide for what you can do
Though if using the solved plugin with one of the various template options you can have these queries in a help topic for example.
Now having signatures have more options added at some point like group & category control options would be very welcome.
With Discourse you can have simple minimal to crazy complex with just about every feature one could think a forum could have.
Something truly archiac though imho is the string threads that Reddit uses to connect comments. I am not fond of. That has been around since Dial up BBS.
Discourse has added a much better feature with being able to focus on a comment where it hides the rest of the topic posts except those tied to a specific post.
