Signature change

[Wit]

At some point, this weekend, SEORefugee is going to implement new Signature rules.

Basically we want to put up a (small) threshold for sigs, in an effort to discourage people signing up for the free links alone.

The signatures for new members have always been automatically 'nofollowed' anyway, but later this weekend people will have to earn the right to add a sig.

This "earning" is not going to be some Sisyphean task, but it will take a bit of time and effort nonetheless.

Alas, we cannot avoid new members losing their current signature in the process. We hope you'll stick around long enough to add them back
