It has all the features you could ask for in a Windows podcast client, but it may still be a little buggy. It's never caused system problems, but it sometimes likes to hang when checking a lot of feeds.
To use this or any podcast client, you want to copy the address of the feed and use it in the program you want to subscribe to it with.
For example, to subscribe to our feed with any of these podcast clients, you would right click the image above and choose Copy Link Location (or Copy Shortcut Location). Then you open the podcast client you choose (Nimiq is probably the easiest to use), choose New or Add Subscription, and then paste the address into the program.
For these earliest podcasts, our podcast feed is: http://www.tollie.org/feeds/techtalk-latest.xml
