I really can't tell. You're the one with the script. Find out where ever the registration process is.
You're looking for a "strlen" determination, on a given players name.

ie.

pawn Код:

new pName[MAX_PLAYER_NAME];
GetPlayerName(playerid, pName, sizeof(pName));
if (strlen(pName) > 12) return KickEx(playerid, "Name is too long.");
