Answer:
   
   First, a good place to start is Jacob Richman's [5]Aliyah pages at
   [6]http://www.jr.co.il/aliyah/. This page will provide links to
   mailing lists for people with questions, as well as information on
   aliyah centers, appliances, housing, jobs, learning Hebrew, olim,
   organizations, useful addresses, web links, and more. You might also
   check the Aliyah forum at [7]Virtual Jerusalem,
   [8]http://www.virtualjerusalem.com/.
   
   Second, the most important thing to know about rights for Olim, army
   service etc. is that the rules keep changing!. Therefore, if you are
   considering Aliya or coming as a tourist and possibly later changing
   your status, go and speak to the local Aliya shaliah and bother them
   about making sure that the answers they are giving you are up to date!
   
   Currently, length of army service is calculated based on variables
   such as age when you become an oleh (temporary resident or citizen),
   age when you become a citizen (after 3 years or more as temp.
   resident), marital status, number of children, and physical profile.
