Your should already be able to connect your LinkedIn account on your profile page. Github, behance and other identity providers of specific industries will be added in the future.
Right now we fetch your name from the identity providers that you connect (e.g. linkedin) and fall back to the user part of your e-mail address if none connected. Being a little experiment, this is the only way to set your name for now (i.e. no manual input). Of course we will change this, if that's what the users want.
Re: payment: Upon ordering a job the buyer transfers money to work.io (via creditcard, paypal or purchase order) and after the job is completed and accepted, all participating users will receive their share in their account-wallet. This earned money can then be payed-out via paypal, check or ACH.
Right now, we're handling disputes/conflicts ourselves and will rely on human support in the future as well.
