I like the idea of splitting them up by generation, it's something we're all familiar with and seems the most logical.
It may be a little too late to do this on the forum though. I feel sorry for the poor soul that would have to sift through all the topics and allocate them to their new home! It's a bit of a digital soup at the moment.
It doesn't particularly bother me that SRF stuff is mixed in with the rest of it, to be honest. In my mind the current subforum is just the place to go for the latest posts on anything Zero related. That's since I lost all interest in 2012 models a few years ago.
I guess that if Brian manages to find the time and make the effort to categorise everything by generation on the Unofficial Zero Manual site, then the same should be done here. Given the appropriate admin rights, I'd be willing to chip in and help sift through the soup and reallocate topics. It would be a nice way for me to help out. I wouldn't wish the job on anyone else though!
Thank you to everyone who helps keep this forum going. I still prefer it to the Facebook Group, even though that is more popular. Thanks also to Brian, who has done such a magnificent job of curating the Unofficial Zero Manual site too.
