GO to line 291 and add there this:
<p><emphasis type="strong">Note:</emphasis> You must identify to the channel before being able to use this command.
</p>

then go to line 526 and be sure it looks like this:
A user can prevent himself from being added as a successor to a channel if he has enabled the NOOP option on his nickname (see <url>http://docs.dal.net/docs/nickserv.html#6.7</url>)</p>  

Now under that add this and translate

<subsubsection>
