Well folks, this has been one of the longest-existing forums for the Xterra and it's been quite a ride, but the time came to retire this group, it had all but fizzled out through 2010 and 2011.
Of course the old content is here for reference, but if you have new questions, there are numerous Xterra sites/forums out there that can be of help. Here are a few to check out:

www.clubxterra.org
www.thenewx.org ----- (for the 2005+ models)
www.xterrafirma.com ----- (an older forum, a bit quiet of late but a solid resource)
www.xterraownersclub.com ----- (another old forum, plenty of good info but a bit chaotic)

These are not Xterra-specific but are also good resouces:

www.nissan4wheelers.com ----- (a western-US-centric Nissan 4x4 community but excellent for technical and advanced projects)
www.nissanoffroad.net

Happy trails!
