You are right, it is a huge task, it's also a never ending task!!!

I would hope to see the site develop in such a way that as conservation changes over time the site would also change to reflect that. We have noticed that sites we start have been edited by other people updating them, not just conservators, so its great to see the "public" (for want of a better word) get involved.
By the way, thanks for checking out the pages...
My advice for getting started would be to start an account on wikipedia... and write your profile. And then discuss things on the talk pages, it's actually pretty easy to do some basic editing, I would recommend doing that to get started... get the feel of things, and then start making more major changes.
Also... Use sandbox on wikipedia to practice... its a useful tool, that I wish I had used before I started... But most importantly, if you're at all interested, and have the time, get stuck in and ask for help as you go. Really the only sure fire way of learning is to do it, make mistakes and learn from them.
Our hope is that many hands make light work, and also that with many voices the vision of conservation expressed can be more accurate and representative.
The photo's issue related to the fact that photo's, similar to e-conservation magazine, need to be released under some version of creative commons. Ideally we are looking for images of conservators "doing conservation".... conserving objects, painting, etc, in labs, or buildings, sculptures, etc, outside.
It'd be great if anyone has images on Flikr that they have assigned as free to use.
We actually came up with several solutions, but, many of us have been too busy to think about the photo's issue for the last few months, I am getting back into it at the moment, and I think that'll be my next issue...
But, if you do have any feel free to email them to me, with their information. check my profile for my email.
