Just a heads up...if you login to eBay (or any other site) with a userid based on your email address, make sure you use a different password for all your sites. If you use the same password/email combination, then hackers will try that same combination at other sites where you could possibly lose money (eg. If your Amazon account is set up with 'one click' to purchase items).
And here's a tip for creating 'difficult to guess' passwords...
Create a password which is based on an easy-to-remember phrase, like MjswPAisi1970
That phrase was 'My junior school was Peckham Academy, I started there in 1970'
Once you have that password, you can make it unique to each site by prefixing it with the name of the site you're logging on to, eg:
Barclays = bMjswPAisi1970
eBay = eMjswPAisi1970
AnswerBank = abMjswPAisi1970
Natwest = NWMjswPAisi1970
