Hi Steve,
To answer your questions in order:
1. Tours are not something currently available on the platform. VAs have managed to setup their own workarounds though by adding each of the legs on a "tour" to VDS in the usual manner, and then creating a custom page showing what the tour consists of. You can then manually verify completion for bonus points, or setup a hidden event to award bonus points on the final leg for example (if you even want to assign bonus points to it).
2. This is not a feature of the platform at the present time I'm afraid.
3. Which logo in particular? Pegasus is a universal app which covers every vAMSYS VA so if you mean the login page, then no otherwise everyone would see your logo even if they aren't in your VA (and the Pegasus software is developed by vAMSYS).
All the best,
Chris
