Don't need to. I fix it on my own now.
I just unable the signature in NAML.
<override_macro name="signature" dot_parameter="do" requires="user">
<n.signature_impl.do/>
</override_macro>
And did this:
<override_macro name="signature" dot_parameter="do" requires="user">
</override_macro>
When this was done, i could easy delite my signature and the remove the override_macro again.
