<cite id="fn_1">[[#fn_1_back|Note 1:]]</cite> In <tt>~[e-mail]</tt>, the <tt>a.b.com</tt> part is known as the "hostmask" and can either be the server being connected from or a "cloak" granted by the server administrator; a more realistic example is <tt>~[e-mail]</tt>. The tilde generally indicates that the username provided by the IRC client on signon was not verified with the [[ident]] service.

<cite id="fn_2">[[#fn_2_back|Note 2:]]</cite> In <tt>usr@a.b.c/home</tt>, the <tt>home</tt> part is a "resource", which distinguishes the same user when logged in from multiple locations, possibly simultaneously; a more realistic example is <tt>[e-mail]/home</tt>

<cite id="fn_3">[[#fn_3_back|Note 3:]]</cite> The Meca native protocol is proprietary, however Meca provides a jabber gateway to connect to the MECA network with basic functionality.
