User Control Panel - Edit Signature

[Haponing]

Hi there,

I wanted to inform the customers that they have to reach a minimum number of posts in order to create a signature. I'm done disabling the signature for registered users, creating another user group with corresponding promotion.

I'm not a coder/programmer so:
First question, How do I put the 'Edit Signature' in User Control Panel of registered users? And second, how do I direct the link to a notice that the user is not yet allowed to post. I understand that you somehow put a 'condition' within the code to make this work appropriately for users who are allowed to create signature.

I really need answers here. Any guidance is much appreciated. Thanks in advance.
