This sounds like a brilliant idea!
We do have the old instructional videos (
https://www.diabetes.co.uk/forum/threads/forum-beginners-video-guides.51729/) but they are pretty much outdated after the last forum update.
Making new videos would be very hard, short term, but a sticky thread in Greetings and Introductions outlining the way the forum works should be doable and very useful!
Making this thread with a group of people who are both very familiar with the forum and have experience with this kind of stuff makes a lot of sense, and we could do is a lot better and quicker using the knowledge and experience of people who are good at this, and not just trying to do it within the mod team.
@jjraak , would you be willing to set up a working thread in General Chat where everyone who wants to can help building a 'How to forum manual'?
I'd be happy to be part of the group (even though I fear I'm a tad too disorganised to write such a manual myself, I'm sure I can be of help), and I think
@KennyA would be very good at this.
