Ebay and Plusnet email

[#1]

My partner and I each have our own eBay accounts. I've changed my email address on my email account to(eg) abcd@anywhere1.plus.net but eBay won't let us use the same email address.
Can I set up another email address such as bcda@anywhere1.plus.com and use them "in tandem"?

You can use any email address you like in the form of whatever@username.plus.com. "Whatever" can be anything you like. Unless you choose otherwise email sent to anything at your username will arrive in the same mailbox.

Thought as much, thanks.
