Internal messaging

$200 COMMUNITY GOAL

2nd runner up from the last vote with 25% and also makes sense to centralize messaging and have record of the chat, unlike on steam that expires within 2 weeks or so.

Also could be extended as notification system that could be use for new bid or listing alerts. eg. when item has a new buy order. seller will get notified about it.

this could lessen scam of hard evidence and must be implemented as message per transaction.

the issue of storage could be fix by 2months expiration after the transaction or when completed it will be cleaned up after 7days when it gets golden check
