So, we have a plan. Users will be able to join LiveJournal without an invite code and have a "trial account" for 30 days. Trial accounts are identical to free accounts, except that after 30 days they won't be able to make new posts or comments unless they're either invited to stay by an existing user (with an invite code) or pay for a paid account. Paid accounts expire to free accounts (not trial accounts), so we're not forcing anybody to keep paying if they don't want the paid bonus stuff. Hopefully this is a fair compromise.
