I use to have an old podcast show and now I want to get back to doing it. I was posting the podcasts through TrafficGeyser which I no longer pay for and don't have access to.

Here is the url so you can see where the source was coming from http://rss-feed.s3.amazonaws.com/51178.xml

I would like to take this over again and start my podcast, but I don't know exactly how to do this. I don't know how I can get access to

1) Change the image
2) Change the bio
3) Upload new podcasts to the channel

I'm really new to podcasting and the technology, TrafficGeyser made it very simple but now I need to take it back and would really appreciate your help.

Thank you in advance.
