ebay - can I add authorised user to ebay account

[charliechump]

My girlfriend's account is doing quite well over here in Thailand selling genuine- non brand name items. So well, that when I go back to UK for a month or 2, I don't want to put it on hold, and of course there's always questions and where's my item? messages.

So, I was wondering would it be possible to add me as an authorised user of the account and then service it from UK?

If not, could I still just sign in from UK (as the only operator) and service messages ? (I guess I could pre-plan advertising or use Auctiva for placing ads).

I've trained her up well to use Paypal, and I think that is best done from Thailand full stop.
