That's the link, right there! 

Yes. you can request a league site through the app. I will also add a renewal form before the next cycle begins. 

Also, the app interface may become the new web interface too. It works well on small and large screens. 

For you iPhone users, I do plan to also make an iOS app. I just need to get or rent some Apple hardware to do it. I'm working on that.
