[OT] quieter EPIC

[* Tong* <sun_tong_001@yahoo.com>]

Sorry for an OT message...

I want my EPIC4 to be more quieter, ie, to ignore messages like
people joining and leaving, mode changes, etc.

In the manual page, it says:

,-----
| To highlight people joining and leaving, mode changes, etc. for a
| channel:
| 
| /ignore #channel +crap
`-----

But I tried all the following which didn't work:

I tried "/ignore help crap", but it didn't work
then tried "/ignore #help crap", but can still see people comming/goning. 
and "/ignore #channel crap", "/ignore #channel +crap" didn't work either.
More over, "/ignore help +crap" doesn't give me hightlights either. 

Anybody knows how to do it? Thanks.
