Lauren, I can't tell you the best way to do what you're trying to do, but I can explain why Dropbox will NOT work for this purpose. When two people share a dropbox, and keep a file in there so that they can both see it, there are actually THREE copies of the file. One on each of their computers, in the dropbox folder, and one in the "cloud". Normally, only one person would change the copy on their computer at a time. When they were finished changing it, that change would be synced up to the cloud, and back down to the other person's computer so that all 3 copies are kept the same. However, with a database, if both are in changing things, they are changing their own copy on their own computer. When they close the database, Dropbox sees that both copies have been changed and has no way to reconcile the changes, so it creates two different copies. So in short, you can't share a database by putting it in Dropbox or any of the other shared cloud drives out there. There ARE ways to share it, which Richard can tell you more about.
