I am new user of Cassandra, starting today.
1) I am unable to join cassandra user mailing list.
a)I did not get any response from user-subscr...@cassandra.apache.org
b) Does it take really long to get subscribed ?
2) I was not able to run Cassandra server on environment described above.

Could not find the main class: org.apache.cassandra.service.CassandraDaemon.
Program will exit.
I was not able to find any solution for this in user mail archives.
User documentation(Getting started) can be updated (FAQ) with solution of above
common error.
If this is not the right place, please re-direct.
