TL;DR:
1) The email needs to be fixed, it's linking to FFXI's policy.
2) The Forum rules should be easier to find and on relevant pages
3) If we can't use the forum then we need somewhere we can buy/sell/trade in game items and services outside of the market board. The market board is good for 99% of stuff, but in cases of selling services (help with quests, primal runs, melding, crafting, eventually repairing) there is lack. This could be something as simple as an additional option in party finder ("services") or a trade chat.
