I have just joined for a year after seeing the product

Hi,

I have just joined for a year after seeing the product https://premium.wpmudev.org/project/pro-sites/

I have setup the multi sites plugin, works great, I then installed the pro-sites plugin and now I'm confused.

After looking at the pages and videos I went for this option because the signup pages look great and easy for a customer to join.

Now for my confusion, Where are these nice signup forms? how do I enable them?
Where do I point my customers to be able to use them ?

Have I missed out a huge step here or have I just got myself really confused?

Could another member help me out here please ?

Thanks
