I just checked out this aite as I too think this is a good idea, but the fact that they want too much personal info and the fact that our government has not been so great at protecting our info makes me think, maybe not that good. I think a better idea is to notify a friend or relative your itin and contacts and keep in touch via the internet.
I will continue to hope that we never need a consulate because the only time we did need them was when we were on the old "Regent Star" that went bankrupt during, yes, during a Trans-Atlantic. Upon our arrival in Pireaus we recieved the following from the US consulate, and I quote:
"Due to the fact that the United State congress does not provide for stranded citizens in foriegn countries we sincerely hope you have the means to get home". (end quote)
At least they said sincerely.
