My friend and I are currently trying to create a webcomic site. We both have wordpress installed on our machines. I have a mac, my friend has a pc. We want to collaborate to make this site. Meaning I can add pages etc when I have the time, and he can add pages etc when he has the time. I went to the users panel in my dashboard and created a username/password for him to use. I checked the box to send him an email and he hasn't received an email. I tried this several times with no luck. Is there a way for use to collaborate in the site creation process. Do we need to purchase a domain just to be able to create the site together. It's kind of dumb if we need to get a host and start paying monthly bills when we are just learning how to make our site. We would greatly appreciate any help anyone can give us. Thanks for your time.
PS: We are first time users of wordpress so we would appreciate it if you guys "dumbdown" your responses.
