Besides DAU, are there any other on-line training sources that can be accessed to obtain CLPs?

An additional source for training to obtain CLPs might be the Army E-Learning training site. The website is at https://usarmy.skillport.com/SkillPortFE/login/usarmylogin.cfm; it contains over 2,000 web-based courses, most of which are 1-4 hours in length.
