OK, so you're just messing around with it. Cool.
ssi_BoardNews, like most ssi functions has a number of parameters which can be passed to change to output.
ssi_boardNews($board = null, $limit = null, $start = null, $length = null, $output_method = 'echo')
If you output it as an array then you gain more flexibility in how it's displayed.
For the page title $context['page_title_html_safe'] = 'My Fantastic Site';
Also there's no need to use multiple php tags. One </php at the top of the page and ?> at the bottom to close it is enough.
