The Global Adopt a JSR program, combining efforts of SouJava and London Java Community,  is an excellent place to get some Java User Group (JUG) resources for JSRs.  It also has the potential to act as an extra set of eyes, ears and volunteers for JSRs.

The Global project to go to is at: http://adoptajsr.java.net.  The wiki page explaining the whole program and benefits to Spec Leads and EG's can be found there, including:

• The mailing list: [email protected] . Portugese speakers-mainly Brazlian JUG members-have their own mailing list and more language lists may be added as required.
• The IRC channel is at adoptajsr on irc.freenode.net
