Is there a way to remove your signature from posts?

i believe sand is right, but if you wish to disable it entirely for the time being, you can edit your profile, click personal, and simply remove your signature entirely. if you want to save the code and wait for a plugin to be devised that toggles using signatures in each post, i recommend pasting the code into the personal notes box below the signature box and remembering to click save. that way, you still have the code, but no one else can see it!

As stated above, the best way to remove your siggy for the time being would be to simply temporarily remove your signature from your posts.

If that option were to be added, it would need to be added from an outside source, or administration in this case.
