I want to second Christopher's request. This banner needs to help us ease our employees through this name change. As the banner is today it does not fulfill that role because A. the linked page is only available in English and B. the linked page is not written for employees at all but reads like a sales pitch for decision makers.
In the Viva Engage AMA you told us that the decision to rebrand Yammer into Viva Engage has been made only very recently. Please stop rushing this or you will burn all the goodwill of our employees, our decision-makers and all of us IT, HR and Comms professionals who championed your product Yammer. You want your product to succeed. We want our employees to succeed. Talk with us to avoid misteps like this!
