New to the blogroll is Numbers USA, an activist website wherein you can obtain information and e-alerts on immigration-related legislation and generate free faxes to your congressional delegation on immigration issues.
The site is by no means perfect. For instance, while of course seeking a reduction in immigration and opposing any amnesty, Numbers USA's style comes off as squishy and moderate. In its eagerness to avoid looking "racist" (and you know it will be called racist anyway), its talking points are quite vague about what the problems actually are. Further, it doesn't allow users to personalize the text of the faxes that will be sent on their behalf, but only pick from a menu of pre-written communiqués.
Still, Numbers USA is the only website that I've found that provides these services. As the only game in town, it is definitely worth signing up for.
