Hello,

Is there some way to not see the following messages when joining a=20
channel? I looked at what documentation I could find, but I didn't yet=20
find a way to silence these messages.

Here are the messages I refer to:

> 14:06 -!- Topic for #foo: foo
> 14:06 -!- Topic set by foo [foo] [Mon Nov 24 11:23:09 2014]
> 14:06 -!- Channel #foo created Wed Feb 23 12:28:47 2011
> 14:06 -!- Irssi: Join to #foo was synced in 1 secs

Thanks! :-)
