Coauthors and revisions
I've changed the way co-authors work, and I've also added in thread revisions. So, geoffrey, when you read this, go into this thread, on the top right (in the main menu), you should see 'edit' and 'history' as pink buttons. Click edit, and edit my thread. Unless you check the option to remove all previous revisions, the old info will be put into the revisions table and the new info stored.
If you have any suggestions on a better way to store the old body text (it's only stored if it's different), such as, maybe what a diff might return? (only the parts that are changed)
Oh well, try it out.
P.S. the 'history' button doesn't do anything yet :P
