You can still access it by going to:
My Stuff > Edit Preferences > Your preferred stylesheet > Choose Talk_Morgan > Then press Submit
If you want to change it back, you can do the same and choose: Talk_Morgan_New
The old style will still have the new logo and rolling banners but the old colour scheme will be in-place.
Thanks Simon!
On a tablet the new format works better, but on a large PC Monitor screen I think I prefer the more muted tones of the old style. I've changed back for now, but will see.
