No offense, but by just reading this I'm quite sure that this project is doomed to fail from the start. Something this big or complex is WAY to much for a beginner.

I bet you don't even know how all things work, that are happening in the background (again, no offenes...).

Besides that it doesn't look like it's something new or exciting, more like just some cheap clone.

...but that's just my opinion, do whatever you want ;P
