Some time ago I tried to start a mailing list* with colleagues from the university, but after 9 messages on June the list died.
Maybe now it can reborn from its ashes!
The list is available at http://groups.google.com/group/eucaliptus and eucaliptus@googlegroups.com and no, it is not a misspell but Eucalyptus in Catalan. (Note: someday to be migrated to eucaliptus.org)
So, feel free to subscribe and lets see if it gains enough momentum.
