This is an open source community driven attempt to create an online office suite. We began last week and have already started coding on the writer/word processor. We only have 6 developers now and we are desperately seeking more developers to accelerate development. Come and join in the fun.
For more info, IM (immediate response) me at saynothingyetsomething@hotmail.com or take a look at the wiki http://ioffice.wetpaint.com/ (wetpaint seems to be down now). The technologies involved are AJAX, HTML and PHP with a mysql database. This is really exciting
