The Mailtags docs say "We recommend deleting or
altering all the MailTags’ smart mailboxes and rules
created prior to the uninstall, as they may have
unexpected results once MailTags is no longer installed.
Any tagged data set in MailTags will be preserved until
either mailboxes are rebuilt or messages are moved.
"

I have a lot of organization tied up in the tagging. If I uninstall then reinstall will it cause a problem?
