+- Charm our "normie" friends, so called, by displaying an attractive contact
+  HTML page, which they can also utilize;
+- Utilize an invitation page, with XMPP capabilities, regardless to the software
+  that powers an XMPP server;
+- Realize that HTTP is obsolete and should be treated as an optional publishing
+  mean, because anything that HTTP offers, is already possible with XMPP, since
+  a couple of decades ago.
