Re: What happens when/if your account expires?
Are you a paying member or just a free one? Your question isn't specific with the circumstances.
If you have a free account it expires in 7 days. A paying account expires in 12 days and you have to wait approximately a week (or less) until you're paid for the days you auto-surfed.
A paying account in which there is no activity whatsoever (without being put in vacation mode) will expire in 30 days. Obviously anyone who doesn't surf at least 1 day, will not be paid at all. The point of profit is reached after 9 days of surfing. Anyway who is unable or unwilling to surf all 12 days is cutting themselves short, because that would give them the maximum profit potential.
We can only have 2 active sets of upgrades at any one time. When one expires, even before you're paid on it, only then may you buy another set.
