I don't know what's going on with PMs. I cleared a lot of them out a couple weeks or so ago to make room, and also changed settings so I'd be notified when a PM came in. I'll check again and try to clear out more, but otherwise, the problem may be with your server or software. You should also have access to my regular email. Feel free to use that (and I prefer it over PMs). (If you can't find my email address, let me know with another quick post here and I'll PM it to you.)
Yes, you're welcome to use the picture. I don't have it in RAW, but I have the original, larger, jpg that this web photo came from. Hopefully that will work. You're also welcome to any of the text. A link that I'd recommend going with your article, which has much more information and a rich variety of ice diving articles originally posted on D2D and which readers might find useful, is at: http://web.archive.org/web/200708172...rts.php?s=3187. If you don't want to use that old webarchive version, I could try to re-post one or more of the original articles to use for reference(s). Let me know.
