At We love Vintage, Do you?, they finally came to an agreement for a team tag: WLV Team (separated). I like how you can make one of yor treasury tags WLV Team because when you click on that tag, it will bring up a list of all team member treasuries. There you can either view by Date or by Hot! (as in most viewed, clicked, etc.)
However, members are still in the process of tagging, so the treasury list by tag there is still short.
For items, it's nice to let shoppers know there is a team network behind our items by a tag:)
