Zoho offers a powerful suite of software tools for creating documents, presentations, wikis, spreadsheets and chatting. It's similar to Google Docs with an added bonus - ZOHO Show. ZOHO Show is an online presentation tool. It's a very practical presentation package and it's pretty full featured. I started using it today and found it to be extremely user friendly. Resizing pictures was a little tedious.
