I have checked in the JIRA on demand admin for each individual project and while there is an option to delete I was looking for some way to sensibly archive a "completed project" meaning the end user has accepted the final deliverables and there will be no more work done on it.
-The follow up to this is we don't want to use up all of our 25MB of space with completed projects, however, we do want to keep some type of record of a completed project...maybe in Confluence as we have no storage limit in Confluence as far as I can find.
-In other tools, like Teambox you have the option from the project admin to archive a completed project but also to un-archive it for any reason.
Thank You!
