Special forms for Supplementary Recommendations?

<p>Should supplement rec. letters be written with a special form? or is a generic letter written on Word/plain paper fine? I don't even think there are special forms for supplement recs.</p>

<p>Thanks for the help :)</p>

<p>Princeton has a special form to use. Here is a link to the form on their Princeton website.</p>

<p>Merci! :)
