I already requested an SVN account.
I didn't see a CSL option in gist. uploaded as text but it's not where users will commonly look for it ( git://gist.github.com/433612.git)

either way, here's the code (maybe someone can upload it. Thanks!):

Thanks a lot for committing and comments.

To complete this contribution there are three other journals share the same style with The Journal of Experimental Biology:
Development
Journal of Cell Science
Disease Models & Mechanisms
(all from the same publisher http://www.biologists.com/index.html)

I am not sure whether users will know to look for the other names. I can change the title, id and link and upload the other three here or to gist if you could commit them. Never mind if it's too much trouble. I can wait for my SVN account.

those should be uploaded as dependent styles -
have a look, e.g. at Acta Haematomica, which just follows Vancouver style:
http://www.zotero.org/styles/acta-haematologica/dev
you get the idea - change the "link" and put rel="source" in there, leave everything after </info> empty
the point is that in case the style changes (or someone spots an error) it only needs to get changed once.
If you want to make the three dependent styles, committing them takes me about 1min, so I don't mind at all.

Edit: and what noksagt says - probably a good idea to name this after the publisher, unless one of the journals is clearly the "flagship"

here goes (all three). Please let me know if there are more comments:

done - thanks again for contributing

it's automatic validation - I'll have a look - not sure what's wrong

I have a style I think will be very useful to many users. Several posts cite the need to call numbers to be included. The Chicago Library List, however, lists call numbers last and does not sort by call numbers, making it nearly useless. My style, Call Number List, puts call numbers first in the bibliography and sorts by them.

I have tried the instructions for mounting it, but they are very difficult, as I'm sure you've heard from other users. So perhaps I could follow the lead of the person who simply pasted the text in a message.
