/* $ModDesc: Provides support for RFC1413 ident lookups */
* Using this framework we have a much more stable module.
*
* A few things to note:
- *
+ *
* O The only place that may *delete* an active or inactive
* ident socket is OnUserDisconnect in the module class.
* Because this is out of scope of the socket class there is
*
* O Closure of the ident socket with the Close() method will
* not cause removal of the socket from memory or detatchment
- * from its 'parent' User class. It will only flag it as an
+ * from its 'parent' User class. It will only flag it as an
* inactive socket in the socket engine.
*
* O Timeouts are handled in OnCheckReaady at the same time as
