+Hi Arnaud,
+
+is it possible to implement a secondary nick option? If I'm connected
+directly to IRC, it would be great if BIP fallbacked to the secondary
+nickname.
+
+I saw that BIP uses the default nickname + a "`". Where could I change
+it to default nickname + "_"?
+
+Thanks a lot for your help.
+Best regards,
+Whoopie
