Allowing our signatures for original posts?

When we initially make a post, any signature that we have does not show. Quite a few people have their products and version numbers in their signatures, but since the signature doesn't show, that helpful information is missing.

Are there any requests filed for this "enhancement" to the Communities? It seems (from the outside) to be a small thing.
Is there a reason that our signatures do not show up when we initially post a question?
