Not sure it is worth a sub-board in each section but I have no problem with people writing these guides. Anything really useful can get set 'sticky' at the top of the relevant board. If you look at the mk2 section that is already happening (thanks to the moderators of that section

). Other sections can get done like that as well. If anyone writes something really useful such as you are suggesting deefadog, just message a moderator to ask them to set the topic 'sticky'.
In the longer term, if we end up with loads of useful info/guides etc then yeah, maybe we look at shifting them into their own section.
