Second i want push notification options in it so when a person gets a message they get notified
And lastly i want the name 'dreamer'changed to Help Tank with the logo!

Let me also tell you a little bit about the app it helps people contact people with similiar interests through which they can ask for help from others
When you login you have to type in a hobby in the search bar and a lost of people who have the same hobby a list of those people shows up and you can instantly chat with them you can discuss the same things and ask for help regarding that hobby or interest!
