hi mobile.
is it possible to put these as JIRA bugs ? instead of just mailing  
them on the list ?

that way people can give them a bit more attention. and other people  
who have the same issue will be easily see what is going on.

the URL is here :- https://issues.apache.org/jira/browse/CASSANDRA
regards
Ian
