This entire week I'm at the U.N. observing the disability convention proceedings. At the same time, I'm trying to close on my new house in New Haven. This would all be impossible if it wasn't for the confluence of two things.
First, the U.N. is almost entirely wirelessly accessible. All of the major meeting rooms have WiFi access. With the exception of the singular lack of power outlets in conference room four (the main meeting room for the convention), it's ideal for multi-tasking with your laptop.
I use two e-fax services to send and receive the many faxes that are necessary to close a house:
Receiving: I use the free efax service provided by efax.com. The free account allows you to receive faxes which are e-mailed to you as multi-page TIFF attachments (which the Mac OSX Preview application can read). The paid account will give you a phone number in the area code (and country) of your choosing (including Japan) as well as allowing you to send faxes. But the paid account is $13/month so I am sticking with the free receive-only account.
Sending: So how do I send faxes? I just found a fantastic new service called FaxItNice.com. They charge only 11 cents a page for domestic faxes and not much more for international faxing. They don't charge a monthly fee, nor do they require any software to be installed, and you can even fax a'la carte. They don't yet list Japan/China/Korea as places you can fax to, but I sent them an inquiry and received a personal reply within an hour from two of their staffers that they are adding these countries (and more) in their next release.
As with all the reviews on this site, I don't receive any kickbacks for promoting either company.
