How can I allow all users to edit posts in one forum?

[simon humber]

I want to allow all my users to edit a sticky post so they compile a list of their needs. One post will be far easier to read than single posts from each of them.

I can't see how to allow them permission to edit this one post I started in the user settings. I am told this is not available functionality in the normal product, is there a mod that does this?

This would just apply to this one thread. I don't want them the ability to edit each other's posts elsewhere on the site.

Thanks,
Simon.

Can anyone at least tell me that it can't be done, so I can move on to look for another solution?
