CB 2.0 vs Kunena forum signature

Hello.

My problem is, that i cannot find any option how to make a field, which other user can edit their forum signatures (kunena). Can someone give me some tutorial?
So how can i edit kunena forum signature via cb profil?

Versions:
Joomla 3.4.1
CB 2.0.7
Kunena 3.0.5

Thank you.

I founded.

But please, help me in another question.
How should i configure the ordering option?
I created field, linked the ordering option to this field, but cannot setup everything in the profil editing option. It shows in the info:
"Select CB fieldto synchronize model ordering from (values: 0 = oldest post, 1 = Newest Post First)"
Its too high for me Where and how should i write this values?

You'd create a select field that has values 0 and 1. Then supply whatever label you want. Example as follows.

Value: 0
Label: Oldest

Value: 1
Label: Newest

I've no idea if post ordering even still works in Kunena though.
