Since someone just asked in the Comments for help with navigating the new EZLN/Other Campaign site, here's some help:
Go to www.ezln.org.mx and click on the right upper graphic ["zezta internazional"].
If you wish to subscribe to the list, click on the third option ["suscríbase"].
Once you do that, there's a language option at the top ["ver esta página en"] - open the drop-down box to the right, highlight English [or your language of choice] and click to the left ["Ver esta página en"]. The English isn't great, but it's perfectly understandable and will get you subscribed to the mailing list.
The zezta page also allows two other options. The first is registering your support by email, the second is registering or commenting on a forum page. The third being the one described above, subscribing to the list.
Anyone still having problems, keep asking, and I'll keep helping.
Cheers for now.
