[GNC] 1) search list 2) gnucash-user at lists.gnucash.org vs gnucash-user at gnucash.org

[Fran_3]

1 - Is there anyway to search the list archives... like maybe you would do an online forum?
2 - I've ended up with two emails addresses for GnuCash...
gnucash-user at lists.gnucash.organdgnucash-user@gnucash.org
What is the difference?Will both get my email distributed to the list members?
Thanks for any help.
