One ebay account matched to an auctiva account. The match is made when you send in your token to the ebay account from auctiva.
In other words, you cannot have one auctiva account and send in the auctiva token to all 4 ebay accounts. A token is you giving auctiva your login and password on ebay. Its a trust thing. One token per account name. I have 2 ebay account, 2 auctiva accounts, and 2 paypal accounts. Paypal requires a different email per account to log in, but I'm using the same bank account on each paypal account.
Hope this helped.
