Web page addresses and e-mail addresses turn into links automatically.
The Glossary module will automatically mark terms that have been defined in the glossary vocabulary with links to their descriptions. These marks depend on the settings and may be a superscript character or an icon, or the term may be turned into an acronym, cite, or abbreviation. If there are certain phrases or sections of text that should be excluded from glossary marking and linking, use the special markup, [no-glossary] ... [/no-glossary]. Additionally, these HTML elements will not be scanned: a, abbr, acronym, code, pre.
If you include a textual smiley in your post (see chart below), it will be replaced by a graphical smiley.
