btw, the sign up process does not ask for email nor mobile number, just username and took less than 10 seconds to make the account co one of my friends signed up yesterday. Which is really cool.
Although they can't really use all the features if they don't have enough RC, so I had to delegate some HP or send some HP for them to power up.
should we delegate some HP for every personal invite until they have enough HP on their wallet from their earnings, you think?
