But I have a couple scripts that I use in an iframe to check whether defined channels are live or not live on twitch and hitbox.
I'll let some pictures do the talking
Twitch Presence Script
The Hitbox script seems a bit urgh.. and it uses the twitch offline online logos. can be seen here
I think this one would need some work.
If you would like this then let me know. I dont want anything for it. I paid for them both a while back now and havent used them in a while either.
mods if this isnt allowed here or in wrong section i do apologise
