In this study, we introduce the problems for realizing an e-learning system available online and outline some ethical issues behind these problems. The difficulties faced to us, when we were going to open Computer Assisted Sign language Learning (CASLL) system online, were one to expose the sign language movies to public with downloadable way, one for increasing the course materials, and one to enhance the collaboration between learners. The ethical discussions revealed that the reliability for the system and the collaborative work for expand the number of course materials were necessary for overcoming the difficulties. In order to realize the reliable and the collaborative e-learning system, we implemented CASLL within Moodle, an open-source Course Management System. For re-designing the system to actual use for sign language learners and teachers, we added new functions to Moodle; the protection function for the right of publicity, the wiki function to enable collaborative course editing and finally the Link function to enhance public relations. We are going to evaluate the system design from the view point of the usability for teaching, the effectivity for learning, and the utility for collaboration.
