Absolutely, Script 360 has comprehensive collaboration features built in.

At Script 360, you are able to send invites to others that, if accepted, provide them with one of the following three privileges:

• Read Only
• Read & Leave Comments
• Edit
• Co-Author

Invitation privileges are based on your Script 360 membership

• Free members: You can invite others to read or read & leave comments on your script.
• Basic members: You can also invite others to collaboratively edit any of your scripts.
• Pro members: You can also invite others to become co-authors, with full privileges (such as creating new drafts, changing element styles, etc) except deleting the script, whichis reserved for you, the original author.

You have control over access to your scripts

With the four distinct privilege settings, you have control over what others can do to and with your screenplays. Most restrictive is to let someone simply read the script, and on the opposite end of the spectrum is giving someone full control over the script as a co-author.
