Quick questionable tip for the trade center

[kumo21]

Is there any possible way to create sub topics within the trade center topic? I think it'd be nice to organize the trade center a little like for ex. have sub categories for classes then each go into each separate to more specific sub categories. I just think it'd make it a lot easier than listing thread by thread and no one looks like past page 2 or 3...

Trade center --> 1. Warrior----------------------> 1. weapon (then weapon has GS and DK category) 2. armor(can have head, body, feet and hands categories)
2. Blader
3. Wizard
4. Force Archer
5. Force Shielder
6. Force Blader
7. runes
8. crafts
9. accessories
10. etc. like bikes, boards, skill books

What do you guys think? Or is it too much?
