Some small tips on IRC (tested on freenode)
====== Nick temporarily unavailable ======
Ok now your nick is Guest42666 and whe nyou try to do:
<code>/nick MyNick</code>
You get:
<code>Nickname is temporarily unavailable</code>
This is a border effect of the enforce parameter. To get everything back:
<code>/quote NickServ identify MyNick MyPassWord
/quote NickServ set enforce OFF
/quote NickServ release MyNick MyPassWord
/nick MyNick
/quote NickServ set enforce ON
</code>
And you are good to go chatting!\\
