here are some basic irc commands that you guys will probably find useful:
/nick <type nickname here>
changes your nick name without having to exit the room
for example: /nick IslandMutts or /nick IslandMutts|afk
/msg nickserv register <password>
registers your nickname so no one else can use it.
for example /msg nickserv register changeme
/msg nickserv identify <password>
once you have registered your nick, when you sign on again, you should identify, or sign in with your password. this allows you to send private messages to other users.
/topic #dogforums <topic>
allows you to change the topic of the room, so that people who are just coming in can jump in on the conversation, or view links that you are discussing etc.
for example: /topic #dogforums The great Cesar Milan debate
/me <text>
emote speak... changes the color of your font to purple and enters your text as emote speak. fun to use.
for example /me sits politely for a greeting as borzoimom enters the room or /me slinks away with her tail between her legs
that's probably all you'll ever need. enjoy!
