For example when Form Toolkit 1.0.1 comes out, will all of those extensions need to be uninstalled and reinstalled in order, or will the extension simply be able to be installed over the old one.
Since there is no next version yet, we should not be able to get an answer now, but it would pay to have that answer ready when an update for any of those extensions is released.
ALSO - It would be a very good idea to either use the General Announcements forum at the TOP of the forum listing or make a forum grouping under the Announcements header for these type of threads.
Important installation info, bug listings, other massive issues (like what is happening with Data Bridge right now) should be somewhere EASY for your users to find - this should be at the top of the forum.. not burried under a Dreamweaver General Topic listing (I would never think to look here.... this topic area is a place for Dreamweaver issues in my mind...)
Please make them easy to find - you barely use the announcement headings anyway, and this would put them to good use. :)
