user signature modifications for posts

Introduction:
Every time you open a topic and read users posts you find users signatures are shown over and over again at the end of every post they do, lot of times the signature is bigger than the post itself that you get confused if its a reply or a signature, it might include big picture which will wash out the topic and make it hard for user to follow and track the posts.

Proposal:
Admin can determine either:
show the signature one time per topic per user.
show the signature one time per page per user.
or keep the default settings to view at each post.

Advantages:
less crowded topics.
less loading time.
better visual reading
cleaner page.

Disadvanges:
cant think of any.
