Hey Mstrlucky74 - welcome.
Trust me - the learning will come fast and furious for someone willing to invest a little time and ask lots of questions.
You will no doubt learn this in time, but a key to getting the best advice on these forums is to provide the most complete information you can about your team and your league. The easiest way to do that without repeatedly typing it in to a post is to put the details in your signature - similar to what I have at the bottom of this post.
To do this, as someone else has suggested - go to the menu bar at the top of this page, click 'User CP (means user control panel)' and then go to edit signature. Be sure to indicate the type of league, roster position and the number of starters at that position, 3C means you can start 3 centers each day for instance. Let us know the number of teams in your league, etc., etc. Keep it updated as changes occur.
With that done, it is easy for others to provide feedback on questions you might have, like: "Should I drop X for Y who is on waivers?"
Have fun - feel free to PM me if I can help in anyway.
