you don't need a web page's help to copy its URL...

There is also something you could do (I've never used tho), it is creating a kata collection

choose your weapon:

• url to the kata
• url to the solutions page
• url to a user's solution precisely
• in the solutions page, click on solutions of users I follow (assuming you follow them)
• there are twitter/FB icons somewhere in the top right corner (never used them, tho, so not sure what their effect is exactly)

not enough??
