My hope was to make this as clean and intuitive as possible from a UX standpoint, so I appreciate your feedback on the design.

As far as future development goes, I hadn't actually thought about linking to one outright. I wanted to get feedback on this barebones version and go from there. Features in the pipeline right now are mobile responsiveness and multiple admins per account. I will have to look into what you recommended as well though.

As far as monetization goes, I just wanted to build something cool that people use. I figure I can always set up some premium features down the road if hosting becomes too expensive but right now I'm willing to eat a couple hundred bucks a month.
