At multiple companies, we have suffered from new and existing users emailing other users or direct email addresses for folks in IT when they have requests (new plugins, global permissions, new user request placed by an existing user, etc.). I've found that placing the admin email address on the logged out home page helps direct new users placing new user requests directly, but not when existing users submit the new user request on the person's behalf or for any other requests they may have. A banner is the most obvious solution, but it is annoying to see it there all the time even when most of the time you are not in the mindset of making a request.
Does anyone have a good way of advertising the admin email address to logged in users other than an ugly, always shown banner? We are using Atlassian Cloud for JIRA and Confluence.
Thanks!
