I agree in principal with svncontinents request, as I have made contact, either by posting a temporary Email adreess for the other party to contact me, or, in one case asking Michelle to forward an Email for me, but I would prefer a more direct and formalized method of communication. I would slo like to see a mechanism to facilitate contact between travelers before departure.
There are privacy issues that have to be addressed however. There have been discussions regarding spoofed Emails. Some people are more sensitive to privacy issues than others, and if functioanlity is too easy to use, it may open the doors to spammers and frauds. At the very least, the travellers would have to be able to opt-out, or better have to opt-in to being contacted, probably with deferent opt-ins for fellow travelers and forum contacts.
For contacting fellow travelrs, once you have the names from the final document package, you can, via the internet get contact information on may of them, but many people would feel that this is an invasion of their privacy. There is a forum for contacting fellow travelers, but those using the forum are aaa very small minority of the travelers.
A related enhancement would be to optionally show trips taken in addtion to countries visited
Before implemeting any such changes the design should be passed by a focus group and initial relase should be trhough a larger Beta test group, as any breach of privacy would leave a bad taste.
