Looking for free ecards

Ack, this is a massive pain in the patoot.

'Tis the season for birthdays. We are set for this year but I am trying to be proactive about next year. It's been more of a struggle than it should have been.

Here's the deal. These are for nephews. One turns 10 tomorrow; the other turned 19 yesterday. We have the following requirements for ecards:

• Free. Not a free trial. Free. Hallmark really isn't free anymore.
  
• No signing up for a service, if we can avoid it. I'll relax this one if I absolutely must, but I'd really rather not.
  
• Safe for tweens and teens. Even though the older one is hitting the big 2-0 next year, it still doesn't mean swearing, etc. are going to be accepted by his parents. And it'd be weird coming from Aunt jes and Uncle reeg anyway. Hence someecards is right out.
  
• Not too froufrou. Jacqui Lawson cards, for example, are lovely but are very, very feminine-looking. Not gonna work here.
  
• It would be nice, but right now I'm not pushing it, for the cards to not be lame. Don't really know a good way to put it, but it's not like we're their grandparents. Hence 123 greetings (which fits the other criteria) is okay but I'm hoping to do better. I went with 123 greetings this year. RP used some other service but we can't recall the name.
  
• Must have scheduling capabilities.

Is this a pipe dream? Please say this stuff exists, somewhere. The younger one isn't on Facebook yet and the elder one is, but he keeps his friend list as his peer group so a Facebook greeting is out in either case.

Shiny red ribbon to the best answer; death by a thousand ecard paper cuts to all spammers.

Thank you.
