I know some forums have a small option for you to change the theme of the forum as long as your logged in. I don't know how difficult it is to implement something like that here, the only forum I ever had myself was a basic text one from years ago. Yes I realize how much that ages me T_T
It would be a nice idea, but currently we only have one theme. maybe once Suyo completed the new color sheme for the new banner? Then we could keep and use this theme with the old banner as alternate style.
Personally I really like this theme, so I like that idea of just being able to change the banner as an alternative. Now you see, I suggest this and if it gets implemented I'll be considered a hypocrite because I'll stay with the default one as it changes lol
