Yes, I think the video above is an excellent run-through of the various features of the site. Keep in mind, though, that GMAT Club is a resource for you to make your own—there is no right way to utilize the vast amount of information available. Some members may get a lot out of watching linked YouTube videos, while others (like me) may prefer to stick to reading responses to questions in the forums and providing feedback. There are even different areas of the site for folks who have completed their GMAT™ journey but are looking for a leg up in the application process. If you joined recently and have already created a post, then you are way ahead of where many people start. I often see posts from some "longtime lurker" or another, sometimes with a "Joined" date that runs back more than a year. And you know what? That is fine, too. We may not all be here for the same purpose, and we do not all have the same social tendencies, but we do share enough to make the GMAT Club community vibrant.
I hope you find the site engaging and useful, desertsafarib.
