Classifieds-make extra fields clickable

Hi,

I would like to move or remove/switch off the initial box created by the classifieds so that it fits with a mobile theme. (the one that shows posted by, created date etc)

I wonder if you could point me to where to re-arreange the layout for this.

Also, The additional fields that are created -

1 can the 'Duration' field be switched off somehow without any likely problems? I do not see a need for this to be shown to viewers.

Are there any plans to make the additional fields clickable eg for email or url?

If not can you suggest if there is an easy way to do this or is it too indepth.

Thanks
