Look for the following in the FORUMDISPLAY template and replace with a vB phrase:
Code:
<img src="$stylevar[imgdir_button]/newthread.gif" alt="$vbphrase[post_new_thread]" border="0" />
To add a phrase, see
http://www.vbulletin.com/docs/html/m...age_add_phrase
and then you could use something like this instead of the image:
Or simply replace the IMG tag with $vbphrase[post_new_thread]
