1. /skill command :: Doesn't give me any information, but doesn't give me an error message either.
It's a Filter, so if you use /skill Fletching, it'll only report your Fletching Skill
Snippet from the ReadMe.txt file:
/skills [filter]
Lists your skills
2. /endmacro :: no text telling me that a macro has ended (didn't it used to do that?)
You're currently set to filter out the MacroQuest text, here's another snippet from the ReadMe.txt file:
/filter macros all,enhanced,none
Filters all MacroQuest output
all: display all MQ messages
enhanced: only display MQ enhanced commands
none: There should be no MQ display whatsoever (not even /who)
Behold what the mighty ReadMe.txt file can teach you, hehe
