Would it maybe be possible after say a month to send people an e-mail about paid accounts, of course we don't want to nag people but some people may not visit the LJ site much, and might not realise how you could benefit from a paid account.
BTW before anyone mentions, I know I haven't got a paid account, mainly cos my parents would go berserk if they knew I had an LJ, thus I have no way of paying :-(( So I have to wait until I am 16 and can get a debit card.
