You can make a comment here without registering so just have a look around. You can comment on most things like news, video, events etc.
I usually make my posts in the Alumni section which is under the "Community" section on the left hand side of the page.
Pleeeeeeeeease do not spam them and ruin it for everybody else.
Keep comments ON TOPIC and take the time to write a quality comment, it's worth it !
All comments are moderated before publishing !!!!!!!!
If your comment is good, friendly and on topic it will get published and you will have yourself a high quality backlink from a PR9 .edu site. It's as simple as that folks.
