Hi Zane.. You just turn off whichever emails you don't want to receive. You do that here

Trade Me in general is all over this. The seller needs to prove compliance in their listings, and be able to provide SDoC on request. Firstly I would report the sellers other items to TradeMe (If they have more listed) and especially if they are "in-trade" You can also make a complaint to both Trade Me and worksafe regarding the item already sold. Or at least threaten it if the seller starts saying they won't refund. Your client can open a dispute for this item on Trade Me from their "Items I won" page.

There are some categories you are not able to change from. Motoring is one. If you have listed in Motoring you have to stay within that. But otherwise you just hit edit this listing and you can change the category on the next page. This is assuming it has no bids of course, if it does you can't edit a listing at all.

You didn't mention what you are selling. The process can be slightly different depending what it is, and of course not everything can be listed as a classified. But for example in vehicles, you are asked which format you want as you list it. See the image below.

Hello bmunga. You cancel it directly with the courier. Then contact Trade Me to get it refunded.  From the help file 

Martin. Trade Me CAN stop you offering bank transfers because with Ping activated and no bank transfer option a buynow can't be made unless the buyer pays with Ping or Afterpay.  Yes, you may be able to do a workaround somehow with auctions and no buynow loaded. But if you have Ping activated, and you will as Trade Me has mandated it, most buyers are going to use it.   There might also be a loophole where a buyer selects cash, but actually wants to do a bank deposit. Time will tell how that is going to play out. 

Gary.  I get and agree to what you are saying about business purchases. Community Groups as well often don't have anyway to make payments except via internet banking. That way they can have 2 or 3 signatories to approve a purchase. Credit and Debit cards are too risky for them to hold.   I think they might have had to leave cash because of the value limits on Ping and Afterpay. You can't add or use Ping for items over $10,000. I think Afterpay is variable depending on the buyer. I've had newbs not able to purchase a $1500 item with Afterpay.  So for buyers making large value purchases cash ...

Yes a sensible idea. The whole feedback system was devised over 20 years ago. Smart phones and tablets didn't exist so everything was done on a keyboard. It was a fairly novel concept at the time. You didn't have huge traders either to begin with so all those robotic cut 'n' pastes weren't there. There have been some trials around the feedback system, including leaving ratings for things like communication, delivery speed,  item quality,  without the need to leave a comment. So it is something Trade Me are thinking about. It's due an overhaul but maybe not really near the top of the "to do"...

Hi Lance. If a bid has been made (and reserve met) the buynow disappears. It is not a recent change. Always been that way. Always will be. You may be getting confused because if the seller has set a hidden reserve, and a bid is made that doesn't meet the reserve, then the buynow stays. There has been no change there either that I am aware of. Again - always been that way, always will be. For example. Auction 3539666735 Has a bid, reserve not met, buynow still available.

Responsible companies seem to be leaving crypto currencies, rather than adding them. Most famously is probably Tesla. There are some issues with it that I can see.  Firstly there is the  purely speculative nature of crypto. A lot of people are likely to get burnt. When you look at with a critical eye, you could say it is basically a ponzi scheme. It is also often linked to criminality and money laundrying because of the anonymous nature of it. Then you need to look at the large energy costs that are expended mining it. Would this energy be better spent elsewhere in an energy concious world?...
