Welcome to the boards Nolan! You'll find all the info you need right here on this site. Don't be shy to post as we are all here to help each other. 

As for updating your profile picture just click on the MY PROFILE tab at the top right of the page. When you are in there you will see an option that says EDIT PHOTO. Click on that and it should allow you to upload a picture of your choice.

While your in your MY PROFILE I would suggest that you fill out everything and get your profile up to date. Titleist is known for sending some free stuff here and there through out the year. It's also good to have so if you have any issues Titleist will be able to assist you better.

Hope this helps and again welcome to the forums!

Cheers Shawn
