I think what he wants is like other forum software, where they mod it to make thread title as link (because these forum software doesn't have weblinks directory.)
Instead of a thread link opens up a thread, it goes to google or any link they want. Like site links where you put URL instead.
Right now the thread title is automatic generated to pair thread_id and forum_id.
Something like this would do:
In Forum thread admin:
1. Add a toggler - thread as link or thread as discussion.
2. If bullet checked for link, using JS to hide thread description and show URL text input. (Or just change the label to URL)
3. Add new column in DB - thread_type small int 1.
4. Thread description can be used to store URL here.
JS:
$('#thread_type').bind('change',function()
If $(this).val() == 1 { $('#thread_description.label').text('URL');
} else {
$('#thread_description.label').text('Thread Description');
}
});
In forum template (output) , hack the while $data= dbarray($result) with a thread_type condition to display the link differently.
That's how I would do it.. Just an idea.
Like I said, core mod is needed because this requires a small modification hack in admin. This was road mapped for forum infusion for v8 if not mistaken... :G
