Hi, i see VB works totaly different compared to SMF

another question just poped up, in all those How-To's its always written
hook location - online_location_process
or hook location blabla,
but... how do i execute a new hook ?
guess with vBulletinHook::
but.. didnt manage how
ps: is it just me or does the search function here on vb.org suck like hell ?
edit:
ok well.. hooks are not performed inside of the new page

just found admincp/plugin.php?do=add
