Unreal3.2.x/Src/s_users.c
dosyasına giriyoruz
Kod:
IRCstats.clients++;
Satırını Bulup
Hemen Altına
Kod:
strcpy(sptr->info,"Bizim Serverimiz Burasi:)");
kodunu ekliyoruz
Sonra değişiklikleri kaydedip çıkıyoruz
Serveri Kapatıp açtıktan sonra Bütün Username'lar Sabit Kalacaktır
Demişsin Fakat user.c de ben böyle bi şeye rastlamadım
