I just made this plugin for this guy here and decided to submit it here and
share it with everyone else as well. Maybe there will be other users that
will find it useful too.

What does this plugin do: With this plugin you will be able to set a
minimum number of posts for your users in order to create signatures.

You can enable and disable the mod from the acp of your forum, where you
can also enter the minimum number of posts for your users in order to
create signatures. By default it is set to 5 posts. You can also choose
which Member Groups and individual users can bypass the limit.

For more, please have a look at the attached screenshots.
