JavaScript: Uno script per vBulletin che non funge come dovrebbe..

Ho trovato questo script, che fa apparire, ai visitatori, un "messaggi di benvenuto":

Ho due problemi..

1) Dopo 15 secondi, si dovrebbe auto chiudere, però questo non succede, e non so perché.

2) Poi, dovrei anche aggiungere del codice che faccia in modo che nella pagina di registrazione del forum, questo coso, scompaia. La pagina di registrazione di vB è register.php?

<a href="register.php?"> 

Io sono niubbo in campo, dunque non so come fare..
Ci sarebbe qualcuno disposto a darmi una mano?
Grazie mille.

Nessuno allora mi può dare una mano?
