i think this will be a really good idea...
Display Poster Information Once helps to reduce bandwidth, loading time and screen space used in phpBB forums by reducing the display of a poster's information to one time per page in topics. The first post a user makes is displayed normally, but posts after that one will have certain images or information removed.
The supported types of poster information that can be removed are avatars, signatures, signature images, rank images, rank titles, locations, registration dates, number of posts, and profile, email, website, and instant messenger links. Left over HTML line breaks that pointlessly take up extra space can also be removed. Exactly what information is removed can be changed when installing the changes or by editing viewtopic.php later.
i would have it remove the signature and signature images after your first reply. load times should be a lil faster
