A new forum has been started by JasonMc and myself for those using AdventureMaker or anyone wanting to build games using Visual Basic.
http://mousepawgames.com/VBGameMakers/index.php
Since no one knows if AM is going to be updated for Windows 7, or "heaven forbid", cancelled altogether, this is an alternative to continue working with other AM members using Visual Basic. I would strongly suggest that you at least sign up just in case the AM site goes down permanently.
At the very least, this new site will show you the possibilities of VB inside AM or as a standalone VB game.
Let us hope that GM will continue to support AM and build a Windows 7 release, but it doesn't hurt to put your eggs in 2 baskets!
