Hey Austin tennis players,
I've incorporated an easy schedule availability organizer tool. All you have to do is click on the link and look at the event.
I chose this tool because you don't need to register up for a new username or password, simply put your name and availability. Then, other tennis players can see your schedule and contact you through commenting or message you.
It will show the WHAT, WHERE & WHEN. You will see a WHO field, you are going to just add your name and for you to choose a time you're available and it will appear on the schedule as being FREE/BUSY.
Also, to show exactly when you're available, this is a TIMELINE/COMMENT area on the right side where you can add any comments so that everyone else can see it.
Below is an example of what it looks like:
