Dropbox and shared folders

Dropbox is a great tool. However I was a bit confused on few things :

• Say you shared a folder with friends to compile together a bunch of pictures. What if, when all contributed to put pictures, you want to leave the share and start to do some removal and editing without bother the others ?
• What if you want to notify all the contributors about something specific to this shared folder ?

I got a very efficient feedback from the support (Ryan) :

"I think I have some solutions for you that will help in exactly what you are interested in doing.

If you would like to send a notification to all the members of a shared folder you can do the following:

1. Log in to your Dropbox account at https://www.dropbox.com/
2. Select the Events tab and select the shared folder from the left side of the window
3. Scroll all the way to the bottom of the page and you will see a text field that says 'Add a comment to recent events feed'

This will allow you to leave a comment to all the members of the shared folder. This will also send the members an email with this comment.

If you would like to leave a shared folder without the other members of the folder to lose the information you can log in to your Dropbox account, select the Sharing tab and click Options next to the folder you would like to leave. From here, it will give you the option to leave the shared folder. Once you choose to leave the shared folder, it will prompt you to either leave the the files on the other users' accounts. This will allow you to simply leave the folder and not affect anyone else.

You can also rejoin the folder at any time by clicking the 'Show past shared folders' within the Sharing tab in your Dropbox account.

Reviving an old project : "Digging Engine"

I found back an old project that allows you to dig holes everywhere. At the end of the day if you made holes everywhere, the caves start to look really cool. The whole level in which I am flying is made by the user itself and not a level that I loaded. You can create miles and miles of caves withouth slowing-down the framerate of the engine. It was meant to be multi-players...
I wrote this digging engine a while back : in 1995. It was made for an artistic project of Maurice Benayoun : the Tunnel under the Atlantic, between Paris and Montreal.
Lots of new cool things could be done nowdays. Sounds like a good plan !
But I need to start by rewriting everything from scratch...
