It seems that there is a problem in the team signature.
(user sig works well).

I get this message:
L'image « [url=http://www.boincstats.com/stats/teambanner.php?teamname=BOINC%20Synergy' target='_blank]http://www.boincstats.com/stats/teambanner...BOINC%20Synergy[/url] » ne peut être affichée, car elle contient des erreurs.

edit:
Now it works...
