reaching out from the in-between spaces...
I've messaged them myself as I was deployed and didn't get the chance to back it on KS. Dimension wrote me back saying they'd send out a pledge manager at which point late pledges would be allowed. I'm still waiting on PLedge manager and hope I don't miss THAT chance as well :-(
Pledgemanager hasn't opened, so perhaps you could subscribe to these forums. That way when the PM opens and all the posts asking about what to get goes about, you'll be notified ;-)
Of course if your deployed and away from the internet...I'm sure someone around here would help you with that.
