ok. this is going to be a serious problem...hhhhhhhh..!
but i think i got something here:
on the main page
www.lineage2.comon the left with the bold headings
on the bottom of those say My Account. log-on
snoop around in there should give you plenty of payment options
i do mine every 12 months(although i'm running out of money)
and you can choose to reaccure them automatically.
so the most important thing is just to punch in those numbers then ur set
and remember we all counting on you boss.
without ur we're doomed...doomed i tell ya(cause as it stands now is half way there already)
