Hello Should I keep or replace the word "useable"? === Place the tenant ID in a useable variable, as follows: === Chapter 9. Managing Projects and Users http://docs.openstack.org/openstack-ops/content/projects_users.html I am wondering to see following article. Is 'useable' preferred in certain regions, or just an alternate spelling of 'usable'? http://english.stackexchange.com/questions/69709/is-useable-preferred-in-certain-regions-or-just-an-alternate-spelling-of-usa Thanks Atsushi SAKAI
