Your message in our Village Pump did not say anything about using the correct logo. Changing the name of a project as part of a new skin is clearly unacceptable. When our present logo was designed, the available width put a real constraint on the legibility, and some time was needed to find the optimal solution.
So I strongly suggest you add an adapted logo to the test version before deploying it. If you want to stick to Oct. 3rd for deployment, it would be reasonable for you to show the adapted logo on Sept. 27th and provide for the possibility to make improvements in the period before deployment. If this proves too difficult, I suggest you state the date on which the new logo will be part of the test version and allow for 4 weeks time to react before deploying.
Although I do expect some long-time users preferring the old skin, after using the new skin for 3 months myself I'm quite happy with the improvements. So I hope my first suggestion will be feasible. This is also the reason for this message instead of asking for a later deployment right away.
