I haven't seen a thread that's compiling all the lessons learned so far while using the forums.
One thing I've found to make it easier when trying to find threads I'd be interested in commenting is to go ahead and "star" the topics. When I log into the forums, I'll click on the STARRED button at the top and it will show me all the topics/threads I've starred and I can just click on them and go there.
So once there is, say a topic about Favorite Restaurants in WDW, I've starred it and I can check it out every so often and comment on it or post a question to it.
Hope that helps. Feel free to post any other shortcuts you've learned the last few days and be sure to STAR this topic if you want another way to stay caught up on it.
