Nice Harmor, I've got loads of uses for this.

any way to put the answer to the field into the thread title?

Not currently, I'll add it to the list of things I need to code into it.

Err... You forgot to put parse html after the post, right ? :paranoid:

All the <br /> show unparsed...

No biggie, just fyi.

Oh, to make the Custom Field mandatory to all posts in that thread:
in the thread just copy the contents of Custom Thread Forms [newthread_form_start] plugin to a new plugin and save it under the newreply_form_start hook, do the same for the Custom Thread Forms [newthread_post_start] (now save it to newreply_post_start) and duplicate the template changes you did for newthread into the newreply template.

Can this be enabled (per forum)

I would love to see some html formating options for the fields. This could be used to submit specific preformated event listings and in the process I would like to resize via CSS images for the final result.

Yes, you set it up per forum.

It sounds like you want real forms, not just a field. Did you check the Forms Hack ?

Wow you are correct! - That forms hack is awesome!
thanks for pointing that out to me .thumbsup.
