Hi Vineet, I watched all your 8 videos, these are helpful and precise to understandable for beginners. Don't you have plan to upload more?

[TheJakeharold]

You're videos are exceptional for people new to this stuff. You explain things really well to beginners, very thorough. I need more!

I was wondering if there is any way of contacting you to ask about specific problems? My email is jake.t.harold@gmail.com

I'm trying to make an app that views pages of a comic, downloads new pages as 'updates', lets users flick through pages and set a bookmark were were they've read to. I was full or worry an hour ago, now I'm full of optimism :)
