Neteller Security Certificate?

[moot]

Yes, I searched (ugh, I hate the search feature), and I'm sure this has been asked before.

Anyway, I haven't been to the Neteller site for a while and when I go there I get a message that the security certificate doesn't match, because one is "neteller.com" and one is "www.neteller.com." Is this any cause for concern? I figure it's probably not...
