You 
can not disable 
format, (!TAGS) and emoticons

 in 1 message!
So, it's still kinda messy.
This would be perfect:
/noformat (to disable format 
only)
/noicon (the only command atm that does, what it supposed to do 

 (according to it's name))
/notag (to disable tags 
only, so in fact the same as /text, but a more suitable name)
/nofilter (for example when sending URL's containing filtered words, would be very handy)
/raw (disables all and everything)
/text command can be removed, or left for time for people that got used to it 
[edit] And make it possible to send 2 (or more) tags in 1 message, just like "/all /close", so everyone can build his own variations of parsing stuff [/edit]
So... Do you want these commands added?
