Speedrun.com added the feature to have subcategories. I was thinking that ror could use it to separate Solo and Co-op runs. This is how it would look http://imgur.com/6RXigGI .

Seems like a pretty cool idea, might de-clutter the category list a bit.

+1 ;)

Problem is, I don't think there's an easy way to port all the runs into the subcategories easily. Correct me if I'm wrong there.

ill check this with JUS (where im mod) there is only 1 run in, so its much more easy to re-submit runs if they get lost

So checked, currently we need to re-submit all runs if we change to the new feature.
