Wiggio may be your answer.
The site bills itself as "the easiest free way to work in groups."
I've found that to be true through my use of the site with other writers. I discovered the site following an online writer's class.
Wiggio allows you to:
- Upload and manage files in a shared folder.
- Allows you to send email, text and voice messages
- Created to-do lists and assign tasks
- Manage a shared calendar
- Host virtual meetings, conference calls and a chat room.
I use the program to keep in touch with classmates from a memoir course and a writer's retreat program. Wiggio allows membership in multiple groups, which is helpful if you are a member of more than one critique group.
In the past, members have set up an online chat allowing writers to exchange ideas, information and updates on his or her work.
If you don't meet in person with your critique partners, how do you exchange information? Do you have a special site to communicate?
