I know iota is new so I will make a summary on how to transfer iota to a desired wallet address.
First you need to download the latest iota wallet.
Iota is new so expect a basic walletm but it works.
The Seed is your username and password combined- its an 81 character combination of capital letters of the alphabet and just number 9.
Now to receive iota you make your 81 character seed and then login to your wallet.
In your wallet tap Receive then tap Attach to Tangle- to attach the address to the network. It has a QR code and the combination of letters and numbers which is the address– copy that combination and provide that to the person who wants to send you iota.
Hope this helps.
