hmmm this should be simple but im confused

[TaP]

when posting a new topic you get to type the subject you want.... well i was thinking... would there be a way to add a box next to the subject box were you can type stuff also and then when posting it would display on the forum page

for example you would have

Subject: [subject box here] Extra Info: [Extra spot here]

and when looking on the forum page would show

Subject [Extra Info]
