I note that on the website, that my sent cards are duplicated. So, I just delete one. Am I doing something wrong to cause this to happen? Thanks!

I don't believe that it is an user mistake. Sometimes I have the same effect as well, also with QSL-Cards from other operators.
You can delete one, no problem. The valid QSO is still activ.

I guess that this effect is a result of short server-delays sometimes. Database / MySQL-Server and so on. Also I get some E-Mails twice.
Not so often, but it happens.

73 and good DX from Jörg :-)

Great Jörg and thanks. I just wanted to make sure that I wasn't doing something wrong on my end - 73, Rick, KQ4Y
