Remobo creates an Instant Private Network ™ (IPN) between users.
It's like a computer network for your social network...
Just login, add users to your buddy list, and Remobo will create a secure network for you to:
Remote control your home computer and access files while at work or traveling.
Privately share large files like photos & docs between computers or with friends & family.
Replace your existing, costly and difficult to use VPN software.
Run games, video conferencing, streaming media, secure instant messaging & more!
Student blogs requiring no email for account setup. Blogs can be private or semi-private (password controlled), and teacher and/or tech admin has complete control.
"Penzu is a free online diary and personal journal with a
focus on privacy. Easily keep a secret diary of thoughts
or a journal of notes and ideas secure and on the web."
Also allows users the option of sharing pieces.
Enter a problem, and a unique URL is created. Once shared with others, a group can collaborate by adding questions, comments, solutions, etc. Very easy to use and effective way to solve problems.
