Introduce a marketplace system

[Fluid54321]

Market place will run off credits.

Username Items:

1. Emojis next to your name (some animated some not, animated obviously cost more)
2. Username items can be sold public marketplace (pier->pier) and will be automatic; similar to other forums where you say what item you want to sell and the price then it automatically deducts the item and take the credits from the buyer to prevent scamming.

Achievements:

1. Create more achievements that can be obtained from using the forums maybe 20-50 achievements.
2. Achievements can be sold on a public marketplace (pier->pier) and will be automatic; similar to other forums where you say what item you want to sell and the price then it automatically deducts the item and take the credits from the buyer to prevent scamming.

I really don't know why features like this haven't been added already just seams like this forum is very behind its big competitors.
