Hi,
Sometimes I refer to another profile in the 'about me' field, using the address and brackets. Example: [http://www.geni.com/people/Kaat-Schindfessel/6000000009734890894 Kaat Schindfessel] . This is very useful. I also use this in several projects. But there's a disadvantage: if the name is changed for some reason (misspelled...), the link doesn't work anymore. In discussions we can use the @ and then search for the right name. So adding this feature to the 'about me' would help me a lot.
