Thank you guys for your nice comments.

If you have suggestions to make this product better, please do not be shy and tell me.

VERY Nice. :)

Thanks, works (Y) :)

It doesnt seem to work, actually, with the link title of pages mod...

Does not work
, see i choosed 14 but every users can edit their sig right when join the forum

Users can edit their signatures, this doesn't prevent it.

What does this hack do?
Prevents putting a "link" to their signature before x posts.

Works with 3.7 ?

Thanks for this, going to add it as I get a lot of spam links in my users signatures :(

Thanks! This is exactly what I needed.

I don't think this works. Started using it a few weeks ago and users with 1 post are still getting signatures.
