Here I've got some errrors:
If a nick holding OP status does !addcmd or !delcmd, it's working fine. Example:
<@David_James> !addcmd !Test Test
<BotComs> David_James, I added Command (!Test) to file.
but when I type !Test, it didn't work. frown

Another error is that, when a regular user try to type !addcmd or !delcmd it showed message like this: * /if: invalid format (line 61, script12.ini)
