trade chat channels

Idea on trade channels. Just some thoughts here. Could they have been named instead of 1-2-3 and so on

/trade currency
buy or sell

/trade gear
buy or sell

and so on /trade currency /trade maps /trade gems

/trade any other idea can be posted no trolls please

would be a lot easier when looking for something or scrolling through to buy sell easier than the random things

Also when u join and leave come back to each channel and still be able to scroll up and see whats been posted when you were away from channel. Having trade chat up while mapping is quite annoying and can be laggy when the spammers of 20 uniques back to back happen.
