Forum Signature

I want to allow my forum users to edit their signature from their profile page.  I would think I could add a custom block to the profile section that would tie into the appropriate language key, correct?  However, I can't find what the appropriate language key is.  Does anyone know?  Is this the right approach?

Is the forum signature a language key?  I am guessing it would not be unless each time a member joins a new language key is added.  This would mean that with 20 million users you would have 20 million language keys added to the site to just hold the member's forum signature.  I would think it would be stored in the database; however, there is a lot about Dolphin I don't know about.

Well, that makes sense.  So, then, it sounds like I won't be able to easily add this option to the user's profile.  Is there a comprehensive list somewhere as to what all is stored in the language keys?

You can look through the language files, they are by the language.php; such as en.php, ru.php, etc.  Each module that you add often have a language file that gets compiled in.

As for the site; some pages are stored in language keys, such as About Us page, and FAQ to name two.

Where is the forum signature option located?

You have to post or reply to a topic and then it's located just above the submit button.

Yes, I recall now.  It should not be too difficult to add the forum signature change thingy to the profile edit page.

I'm all ears.  Any help would be very much appreciated.

I have so much going on.  I will look into this.  In the meanwhile, if someone else wants to present a solution, then please do so :-).
