Thanks, Derek; we usually open up the BETA forums during testing. I know the Zachery is working on the 3.6.0 version of vBGallery and could probably use some testers, but since you are using PP that won't help him.
As for PhotoPost, I've already started on the next release, which you can see at: http://www.viperalley.com/gallery/index.php
and we should be doing some kind of BETA in the future when it's ready.
(Notice the new AJAX features for the calender pal on the main index and then on a showphoto page the use for filmstrip previews, exif information and other items for photo administration. Also trying out "uniform" thumbnails which resize and crop from the middle.)
