Husband signing divorce letter

Q: In a heated argument with my husband, I wrote out a letter of divorce stating that he (his name) hereby issues me (my name) with a divorce and forced him to sign under his name. He signed in anger of what I was asking. I know that this is wrong. I would like to know if it constitutes to a divorce as I do not want to live in sin.

Earning through YouTube

Q: My question is related to earnings from YouTube. YouTube was blocked in Pakistan because of blesphmous content now it is unblocked after launch of local version of YouTube.

So suppose if YouTube remove this video but we are not sure wether it's still available to view in other countries... Keeping in my mind these things. Earning money from YouTube is allowed or not?
