There is an arcade mod available to install,please vote on this poll if we should install a one or not,thanks,admin.

What poll?
or do you just mean make a post saying YAY or NAY

I vote 'MEH' don't care either way really, an arcade can be a distraction.
The main plugin's you want to be looking for are the one that enbeds youtube videos automatically into posts, the one that re-sizes images to a certain size in posts, I'll look into what they were called if it helps.
