I stumbled across your post, and had to re-register here to get an account that could post. I last posted at Luminous Landscape in 2004.
Anyway, it's been a bit quiet on the GreasePencil front. I got a fair amount of feedback about the beta version at RG, as you probably read, and I am trying to come up with a way to simplify the usage, and guide people through an edit without them having to think about how GreasePencil works, and about what visual treatments will get this across. So, I have some coding ahead of me to further improve it and get it ready for prime time.
If you've got additional feedback for me, bring it on! Greasepencil is still demo-able at http://grease-pencil.com/
I haven't ponyed up for the RG/Pro Photo forum subscription, so if someone has, and there is activity on that thread, let me know about it. I did save out the RG thread before things switched over, so I have that if anyone wants a copy (A Mac Safari web archive, I think). I understand the old posts should still be viewable at the new location, but haven't figured out how to get there yet.
It would be great to see this initiative discussed here, and I would be grateful to know of the project's progress. Does anyone have any news?
I'd love the discussion concerning Greasepencil / similar to be decanted to this forum. I really am missing the buzz and candour of the old medium format haunt, and I believe it is important that we revitalise / transpose those erstwhile, yet incredibly-useful threads.
