Zoho
I highly recommend Zoho
to my coworkers for their use, and their students use. The Zoho Office Suite is a
Web-based online office suite containing word processing, spreadsheets, presentations, databases, note-taking, wikis, customer relationship management (CRM), project management, invoicing,
and other applications developed by ZOHO Corporation. It was launched in 2005 with a web-based word
processor. One of the strong points of
Zoho is that you can use all the Microsoft office programs online (free!) and you can collaborate with your fellows online. Zoho
applications are divided in three groups: Collaborative Applications, Business
Applications and Productivity Applications.
v
Collaborative Applications:
chat, docs, discussions, mail, meeting, project and wiki.
v
Business Applications: assist, books, bug
tracker, campaigns, creators, CMR, invoice, live desk, market place, people,
recruit, report, site 24/7 and support
v
Productivity
Applications: calendar, notebook, sheet, writer and show.
Sumo Paint
Sumo paint is an easy and fun image editor tool; you can use it online without having to install nothing in your hard drive. You can edit and share images as a professional just like Photoshop. Sumo has many of the same tools of Photoshop, but Sumo is more addressed to work with illustrations than with heavy images. The advantages are that first, it's free, second, is easy to use, third, you can work online making it easy to share.
