Hi! First of all thank you for this forum, I'm so new to this iptv thing etc.. I discovered it about 3 months ago and I absolutely love it. I'm learning my way around Slowly. Looking forward to learn a bit more from you guys and it looks like I got a lot of reading to do...

BIG Hello from Gothenburg (sweden ) I am new to IP TV and IKS field but I hope learn a lot about it.
