You have to remove the spaces, and write in your username. And Xrunners did not work (in the other thread), because the link continues into the next line.
ALL. The spaces. Anyway, do you know how to make a regular link? Just like here on the forums. First you push the "Link" button, put in the link. Press ok. Write "To messenger". Not press the "Link" button again. Copypaste what you just wrote, and put it in your about.
