I would like to rebrand "Personal Spaces" in my instance to be "Sandbox"
Result: Anywhere 'Personal Spaces' is displayed in the UI, replace it with 'Sandbox'

Reason: We are using Personal Spaces as a Work in Progress space for individual's task. A 'Personal Space' is open by default and we'd like to keep that as is. 'Sandbox' is easier to communicate to new users of Confluence and intuitively denotes the openness of the users own space as well as it's purpose to share openly with others the work in progress.

I've not been able to find existing documentation on how to edit this aspect of my Confluence instance. Seems like it would be easy enough changes....if already available can someone point me to existing documentation steps? Thanks!
