WYSIWYG Editor for Forum Signatures?

So i'm not sure if this is possible but can a WYSIWYG editor be put in for forum signatures.

The support for this is already there it's just missing the editor 

(as you can see here)

This is what i had to put in the signiture:

Having to bump this as I can't find any way to both add the TinyMCE Editor or increase the forum signature length as there is no control panel for this module. 

Anyone have any idea on this at all?

For the length part; in signature.xsl find:

<input class="forum_form_field bx-def-font-large bx-def-round-corners-with-border"  type="text" name="signature" style="width:70%;" value="{$text}" maxlength="100" />

The part I have highlighted in red is setting the number of characters the input tag allows.  However, I have not checked to see what the database allows for that field.

Also, I don't know if the signature is sent through the htmlpurifiier or not; maybe others can answer that question.
