Krishantha,
Thanks for joining up. I look forward to viewing your organizations education materials as soon as possible! BY the way, can you upload a photograph (or graphic of something if you are shy) as the image currently associated with your profile is a generic one, rather than one individual to you! If you go to your profile by clicking on the 'My Page' button, you will see a link that says, upload photo their! Hope this helps! There is also a video which shows you how best to use the site and upload resources or even videos! Click here to get started!
