eCard on V 2.2.4 - send to multi. email addresses?

I'm running G 2.2.4 and have it up and running.

I have the eCard module and it works fine as well.

Is there a way to sent to mulitple email addresses at one time?

I've tried to use commas and semi-colons in between the two email addresses, with no luck. Just get an error message that says invalid email address.

Any ideas? I've poked around the FAQ and haven't found anything.

Thanks!
