Thank you for responding LB.
Yes, they are very nice styles.
Re current, the phpBB styles database lists them as 3.2.2. I figure that means the extensions are working?
I don't know if Arty will read this but I wonder if there is a way for the user to modify them to CSS. There are online converters for such.
Perhaps I should send an email to Arty's website, or maybe I could try to duplicate style in all CSS.
