How do I use the entry title or other information in my page <title>?
You can easily do this on any of your “single-entry” type Templates (i.e. “comments”). Simply use something like this:
<title>{exp:weblog:entries rdf="off" limit="1"}{title}{/exp:weblog:entries}</title>
Note that you can also use this method to add the content from other fields in addition to just the {title}. Simply use the same method and put in the field of choice. To display custom field information:
<title>{exp:weblog:entries rdf="off" limit="1"}{custom_field}{/exp:weblog:entries}</title>
To put date information:
<title>{exp:weblog:entries rdf="off" limit="1"}{entry_date format="%d %m}}{/exp:weblog:entries}</title>
To display categories:
<title>{exp:weblog:entries rdf="off" limit="1"}
{categories backspace="1"}{category_name},{/categories}
{/exp:weblog:entries}</title>
