[TECK]

i understand now.. just edit your file yourself is really realllllly easy this.. something like that:

$article[editthread] = '';
if (ismoderator($article['forumid']) or $getperms['canopenclose'] or $getperms['candeletethread'] or $getperms['canmove']) {
  $article[editthread] = '<a href="' . $bburl . '/postings.php?s=' . $session[sessionhash] . '&threadid=' . $article[threadid] . '&action=editthread">Edit Thread</a>';
}

however this is just terrible for the performance because of this:
the ismoderator() function performs a query to check and see if you have actually perms to edit the thread. if you place a link like that in the articlebit template, for every article you display it will add a query. so if you display 10 articles you will have 10 queries extra.
it's called query in a loop, the worst thing a coder can do. you can mess a server easy if you have a busy site.

if you want to ruin your page doing what i typed me above, dont come and complain the sever is really slow...
--------------
now for the second part related to parsing, i have no idea what you are trying to do or say... sorry.
you want to display an event from a group of forums on a single page? do an array, something like that:

if (in_array($article['forumid'], array(2, 15, 48))) {
  return true;
} else {
  return false;
}

or you want to run a query?? to grab them from those forums... ? let me know...
