I wonder if anyone has developed a module which can send a online greeting card to one or more members, using exsting free online services, such as Yahoo!Greetings. Ideally, it can send greetings in batch to a group of users...

Xmas is coming fast, I really love to send a xmas to all our members, but I'm afraid I don't have enough time to write a module from scratch. If anyone has done something similar, even not quite finished, I'd love to take a look.

Thanks a lot in advance!
