Although I think this forum needs more sub-sections to keep all this information as organized as possible, giving level 2 users the ability to create their own sub-sections will likely cause disorganization to the point its better to not have any sub-sections at all.
There are lots of "Member" (trust level 2) so that's a lot of possibilities for disaster.
However "Regulars" (trust level 3) have worked hard to earn their status and are the most reputable users on the forum (aside from admins). If anyone should be granted the ability to add sub-sections it should first be tested with "Regulars" (trust level 3) first.
Regardless, anyone has the ability to request a sub-section on the forum by posting a topic in the section below. It will be reviewed by an admin, and then if they think it is a good idea, they can then proceed with creating it.
If there are not enough posts currently on the forum for that sub-section the chances of it being created are very small.
If there are a lot of posts currently on the forum for that specific sub-section (such as Guides/Tutorials - one of my requests) then they should have a high chance of being created.
In the end it is still up to the Admins to make the call.
You are more than welcome to request a sub-section by creating a topic in the section below:
