Careful debating lead up to this, but I figured there's no other way to go about this.
I present to you - a third party forum for taking mods on osu! beatmaps!
http://vert-maps.boards.net/

Please read the FAQ thread on the forum before doing anything on that site ever.
But yes, everyone is free to post there - you do not need an account! (unless you are making threads for your own maps)

I am not expecting that to succeed at all, but for now - it's a compromise I'll have to deal with.
I will also slightly tweak the website in favor of that forum's creation as well.
