Today,I found a Open Source project like ours exactly when I view the content of a open source UML tool named argouml at http://e-learningcommunity.tigris.org/ and http://argouml.tigris.org/.
the main goal of this project is e-learning,exactly like our learndiary.the definite diffirent between these two is:e-learningcommunity implemented with PHP,ours is JSP.
Maybe,we can move our work in this group.Because it own an integrated method for web development.
