I'll likely comment on your NL cash game hands if you post them.
Now, a warning: I'm about to go into more detail about forum signatures than is necessary.
You're correct -- a signature
modification is reflected immediately on almost all posts, except the old posts that
never had any signature at the time of posting, regardless of whether there is a signature on file during the viewing of that post.
I was creating a signature (with no current signature on file), and that change isn't reflected on old posts, unfortunately -- there must be php code that is hard coded into the post structure format when it's submitted which
calls the
function that inserts the current signature on record, but the code to even call the signature insertion function is not included if there is no signature at the time of posting, regardless of whether there is a current signature on record.
I'm explaining this because I'm fairly sure it is something that can be fixed rather easily with a few minor modifications to the code.
