+|---------|------|---------|-----------|
+| **CHMODE_a** | +a | Admin only channel | Doar admini canal pot vorbi |
+| **CHMODE_L** | +L | Redirect overflow | Redirect users când canalul e full |

+| **CHMODE_T** | +T | No notices | Blochează /NOTICE în canal |
+
+**Impact:** ⭐⭐⭐⭐ Important - Control avansat canale, protecție extra
+
+#### **EXEMPLE PRACTICE:**
+
+**1. +a (Admin only channel):**
+```irc
+# Creezi un canal doar pentru admini canal:
+/JOIN #staff
+/MODE #staff +a
+
+# Acum doar cei cu +a (admin) pot vorbi
+# Ceilalți văd mesajele dar nu pot scrie
+
+[User normal încearcă să vorbească:]
+<UserNormal> test
+[ERROR] #staff :You must have channel admin (+a) to speak
+```
+
+**2. +L (Redirect overflow):**
+```irc
+# Canal principal cu limită:
+/MODE #lobby +l 50
+/MODE #lobby +L #overflow
+
+# Când #lobby ajunge la 50 users,
+# următorii sunt redirecționați automat la #overflow
+
+[User51 se conectează]
+[10:31] -!- User51 redirected to #overflow (channel full)
+[10:31] * User51 joins #overflow
+```
+
+**3. +O (Opers only):**
+```irc
+# Canal secret pentru operatori:
+/MODE #opers +O
+
+# Doar IRCops pot intra
+[User normal încearcă:]
+/JOIN #opers
+[ERROR] #opers :Cannot join channel (IRCops only)
+
+[Operator:]
+/JOIN #opers
+[10:32] * You joined #opers    ← SUCCES!
+```
+
+**4. +Q (No kicks):**
+```irc
+# Protejează canalul de kick-uri:
+/MODE #protected +Q
+
+# Acum nimeni nu poate da kick, doar founderi
+[Operator încearcă:]
+/KICK #protected BadUser Get out
+[ERROR] #protected :Cannot kick users (channel is +Q)
+
+# Doar founderii pot da kick
+[Founder:]
+/KICK #protected BadUser Get out
+[10:33] * BadUser was kicked by Founder (Get out)    ← SUCCES!
+```
+
+**5. +S (Strip colors):**
+```irc
+# Canal fără culori (profesional):
+/MODE #business +S
+
+# Codurile de culori sunt șterse automat
+[User trimite:]
+\x0304,02RED TEXT ON BLUE
+[Alții văd:]
+RED TEXT ON BLUE    ← Fără culori!
+```
+
+**6. +T (No notices):**
+```irc
+# Blochează /NOTICE în canal:
+/MODE #news +T
+
+# /NOTICE nu funcționează
+[User încearcă:]
+/NOTICE #news Test notice
+[ERROR] #news :Cannot send notices to channel
+
+# /MSG funcționează normal
+[User:]
+Hello everyone!    ← MERGE!
+```

+```bash
+cd ~/ircu2
+
+# Pull ultimele modificări
+git pull origin main
+
+# Checkout pe v1.7.1
+git checkout v1.7.1
+
+# Verifică că features-urile sunt adăugate:
+grep -c "WHOIS_OPER" install.sh     # → 1 ✅
+grep -c "WHOIS_ADMIN" install.sh    # → 1 ✅
+grep -c "OPERMOTD" install.sh       # → 1 ✅

+
+## 🔍 VERIFICARE DUPĂ INSTALARE
+
+### **1. Verifică în ircd.conf:**
+```bash
+grep "WHOIS_" /home/ircd/ircd/lib/ircd.conf
+grep "OPERMOTD" /home/ircd/ircd/lib/ircd.conf
+grep "CHMODE_" /home/ircd/ircd/lib/ircd.conf
