Hey thanks for following up man. I appreciate it.

1. Posting was bugged. It was a very dumb mistake but it's fixed now. Please try posting again.
2. Yeah the profile picture field doesn't get filled in automatically, but it does actually update. You can check out the json_metadata field here to verify https://steemd.com/@georgedonnelly
3. Yeah the voting power slider allows you to upvote more than just 20 posts with maximum power per day. The support the developer is if you want to upvote the MasterThread each month thus supporting me.
4. Yes a scheme like this is in the works. @fabien is working on a project called steemconnect and I will be one of the first developers to implement it once it's finished.

Thanks again!
