Hi mate,
yep, it will accept comma separated lists of names, added a new bit last night so if you can't add a film in one sitting, it's easy to get back to the ones you've entered. There's a "draft" link in the top left that shows a count of your draft films, just click on that to see the list.
We go through all the entries during the day, and add things we know about. When a film gets in a good enough state, we take it out of draft, but the original person that entered it can still amend the details.
thanks
Nick
