Potom do textového pole napište důvody, proč by měli admini provést vaši žádost, problém nemusí být patrný na první pohled. Odkaz na příspěvek bude přidán automaticky.

Offtopic diskuse použijte pro diskusi mimo záběr našeho portálu (včelařství, windows), která by měla být smazána.
Duplicitní diskuse je určena pro případ, kdy uživatel odeslal svůj dotaz několikrát.
Návrh na cenzuru použijte, pokud komentář obsahuje urážky, vulgarismy nebo porušuje zákony.
Návrh na smazání komentáře je velmi neobvyklá akce používaná obvykle při nepovolené reklamě či spamu, výkřicích psychicky nemocných jedinců (ještírci) nebo pro smazání duplikátních komentářů.
Oprava formátování je žádost pro úpravu formy příspěvku, například pokud někdo píše bez odstavců nebo použije PRE pro celý komentář. Žádosti o změnu obsahu budou zamítnuty.
