$template_main_menu = <<<EOT
<span class="topmenu">

<a href="my_link.html" title="my link description">my link text</a> ::

and as a new side can make
Sorry, but I don't understand what you are asking.
Please try to explain fully what you are saying. Don't worry about how good or bad your English is, we understand many have problems with it.
in case your question was "how do I modify this link to open in a new window", here's the answer:
Change<a href="my_link.html" title="my link description">my link text</a>
to<a href="my_link.html" title="my link description" target="_blank">my link text</a>
This is of course not coppermine related, but pretty ordinary html...
