Signature editing in Frontpage

Hi Zorz, Hi others =)
I use GD bbPress Toolbox Pro amongst other things to display a Signature in the Forums. Thats all fine, but there is no “Edit”-Funktion in the Custom Profil-Pages of Buddypress. So the Plugin-Author provided a implemention-guide for those themes they use custom styles e.g. Arcane.
I have to use this to display the Signatur Edit form:
gdbbx_display_signature_editor_form
I have add it above the “Aboutme” field. All works…

But now, i have a add server side code where it handle the saving of my form. I have to call a function to save:
gdbbx_save_signature_from_post

But here is my Problem, i don´t know, where to place it, or how to call it right.

Can u please Help me.

(I know this is not a arcane bug/fault, but the Plugin-Author don´t give help on custom themes.)

Thanks!
