Just getting into mining, seeking advice with Public-Pool.io

I bought a usb hub kit of seven T-dongle S3 usb miners. Setup a wallet and was looking to setup a solomining pool on public-pool.io for the 7 usb sticks. But having trouble setting up an account. It requires a btc address, worker name, and password for a login but i dont see an option for signing up to create an account. If anyone has used the software id appreciate any advice. I was attempting to set up the pool before the miners so i could label the sticks as i set each one up.
