I think it's a great idea to have 2 streaming sites, too much material for just one site and ultimately more scenes will be released! which can only be a great thing
PLUS! for whats on the custom streaming site now, you would have to wait like 7 months to see all of them on Mostwam TV... But Now, you can see then right Now
So for example, if Charlotte releases a new update. it could take up to 3-4 months before it's up on Mostwam.tv
From what I heard they want to replace the slot they saved for the Charlotte's updates for a new Casual Wam update. (Which being a fan of Casual myself I won't objected to.)
If I were you, Subscribe to Mostwam.tv for a month catch up there, then Subscribe to Customwam.tv (I think that's what it's called) catch up with the content.
