Additional Entry Fields for Blog/CMS Article Commentators

[Mondi]

Hi all,

I was wondering how to add at least one extra field to 'comment areas' which guests - not registered members - must complete before they can publish their feedback or commentary.

I'll be allowing guests to leave comments on my blogs but would like to grab their email addresses.

A Solution-de-Luxe would be a mod that sends the commentator a nice Thank You email once her/his commentary becomes published.

Any suggestions?
