I think, if you're going to change anything at all, you should make the entire Minishops forum into a Major Category.
Like:
Category: Minishops
--&General (The shops that sell a little of everything)
--&Art shops and Requests
--&Breedables/Changing Pets (keeping it's RP subforum a sub under it.)
--&Personalized Graphics
--&Services
--&Minishop Q & A (What is now the Pricing, Assistance and Suggestion sub-forum)
--&Freebies (Where all the shops that are only free stuff go)
--&Auctions (Where all auctions of things that can be found in the minishops would go)
I don't think just one or two things should be moved - if Gaia does this, it'll probably just confuse a lot of people even further.
Where as, if Gaia were to make minishops into a category of it's own, they could categorize everything a little easier, and as a bit of a small bonus, make things easier for the users.
But then again, I'm just a Minishop Owner, I don't know anything - I just run a minishop.
And I don't get much business being buried under two levels of forums in a Category that has nothing to do with anything that makes up minishops.
