Ok, if everyone is only going to give one name, then I don't see the use of this. Come on, at least 10 names (if you have that many friends

) Don't worry about privacy, you don't have to give their email or phone nr. And if you're still worried about it, then mix up the names and surnames or something.
I'll give an example:
Thomas Bindels, Belgium, Club Brugge, 06/04
Sacha Kerremans, Belgium, Cercle Brugge, 08/01
Birger Wackenier, Belgium, KV Oostende, 13/11
David Logghe, Belgium, Club Brugge, 26/02
Sam Vandecasteele, Belgium, Standard, 15/03
Robbe Vansteelandt, Belgium, Club Brugge, 01/06
Arne Van Belleghem, Belgium, Roeselare, 29/08
Korneel Maes, Belgium, Club Brugge, 17/02
Remco Acke, Belgium, KV Oostende, 05/09
Yoeri Jonckheere, Belgium, Club Brugge, 22/07
Nicolas Sigafoose, Belgium, Club Brugge, 03/03
Rayan Azzi, Algeria, 02/12
Mathiz Serlez, Belgium, Charleroi, 16/10
