I did this place
where to change this oval?
It might be in the CSS of the theme, seeing as it isn't the default theme.
forumdisply_threadlist , showthread templates that what I saw in the pictures you posted..
so it's those templates
no I can't give codes..
you must post this templates here to allow me to modify it for you..
but anyway that will not guarantee correct result since it's depend on your total page layout..
I don't think he wants the theme
honestly I don't have too much time to do the whole changes for you.
as I mentioned above the both templates well need to be edited
u will just do the same modification that you did in the index page (like the 1st picture you posted)
