I would like to add a field in the registration form, and then reference the contents of that field in the templates.
Specifically, I would like to add the Website Name, after Website URL in the registration form. Then on entries, I would like the entry to say, Posted by Carole of Carole's Kitchen, with Carole linked to the user's profile (as is now) and Carole's Kitchen linked to her website's URL.
Right now when someone leaves a comment, there is a little MT icon that is linked to the commenter's URL.
Question is how to create a field on the registration the data content of which can be used in the manner described.
I've added the following code to the Registration template in the System Overview:
<mtapp:setting
id="website-name"
label="Website Name"
label_class="top-label"
hint="The name of your website. (Optional)">
<input name="website-name" id="website-name" class="ti" value="<$mt:Var name="website-name" escape="html"$>" />
</mt:App:Setting>
but I'm pretty sure that's not enough to do the trick. Ideas?

Well, I created a custom field and tied it to the user data. So now I can enter this information in my profile edit window.
But I still haven't figure out what to do about the registration form. I would like this field to be there at registration.
Hi, Afraid from my quick spin around you need to be looking at a few files:
lib/MT - Author.pm - Association.pm - Auth.pm - Comment.pm
also look at the lib/MT/CMS & lib/MT/Auth folders. Afraid IMHO MT has a weakness with the 'User' registration side of things, as in ot all users need to comment and not all users are Authors but MT doesn't really handle this very well.
I'll take a deeper look and see if there is anything else I can find.
Hey, Elise. Brad checked something in a couple minutes ago that on quick scan looks like it might be exactly this. I'm assuming it'll be in the RC4 release slated for next week, so if this question is regarding the site I think(which is currently running RC3), you might have Jesse take a look at it.
