My city/town/suburb/... is not in the list of Web of Trust locations

This list was taken from a kind of official list of cities, countries, etc. Some users report missing cities but currently there is no "add my city" function. As a workaround it's recommended to pick a bigger city close to the missing one.

There is an open bugreport for missing cities and you might want to add yours to that list. See ContentReviewTeam/case0030

I want to list my name in multiple Web of Trust locations

Currently there is no such function. See ContentReviewTeam/case0024 for the corresponding feature request.

Are CAcert digital signatures legally binding?

If you live in the U.S. then Digital Signatures can be used in legally binding agreements (President Clinton signed S761, "The Millennium Digital Commerce Act", June 30,2000). As with any contract, *BOTH* sides must agree to its provisions, including enforceability of digital signatures.

IANAL - see http://www.techlawjournal.com/cong106/digsig/Default.htm for more information on applicability of digital signatures to U.S. law.

Please seek qualified legal counsel for a thorough determination of applicability. With the law, an ounce of prevention can be well worth the time and money!
