Read functionality is coming!

Call for help!

If any of you care to see this project continue to develop, I would love to have any and all help. I all but completely gave up working on the project for the last month or so because I needed to try my hand at different projects. It seems I'm unable to give it up completely, though.

Email me via and let's get to it!
