Bill,
I have mentioned this to you before and I wonder if you might consider it again. I love Guide and have since version 3.0 and have touted it's benefits and usefulness to countless friends and fellow amateur astronomers. I have even taught groups of user and potential users how to use some of the special features of Guide. I also like using Deep Sky Planner 5 and I like the way in which it interfacing with certain planetarium programs like Chartes du Ciel to show charts of observing lists.
I have always thought that Guide & Deep Sky Planner could make an incredibly dynamic dual. I would like to ask you again to contact Phyllis Knight (knightware@...) and see if you can work together to add an interface that allows the two great programs to work as one.

Thank you for at least considering this,
Long Time Guide User
