For the longest time, on b.net, I didn't know how to utilize the commands that help you navigate the site. Below are some of the commands I know. Most veterans to b.net already know these, but I figured this could be a helpful tool for beginners.
All commands start with the slash " / " followed immediately by the command which is always one word.
/whois <name> - This command will locate said person and reveal their acc# to you
/whereis <name> - The same as /whois for all intents and purposes
/who <channel> - Will list all the names of the people in a certain channel
/join <channel> - Will cause you to join said channel
/rejoin - Rejoin the channel (can help lag sometimes)
/ignore <name> - Cause said person's msg's to be invisible to you
/unignore <name> - unignore
/squelch <name> - Same as /ignore
/designate <name> - [Channel Op] Designate a new heir for the gavel in a private channel
/kick <name> - [Channel Op] Kick user out of private channel
/ban <name> - [Channel Op] Ban a user from a private channel
/unban <name> - [Channel Op] Unban a user from a private channel
Also note that the names after the commands can be replaced with the account number preceeded by the pound sign. Example: to find me you would type /whereis Ash1138 or /whereis #642947 to find me under any name.
