Well mate, seeing as it is you

.. design yourself a signature pic, and either upload it, as an attachment or send it to me, and we will see how big it is, in both pixel & file size .. if it is ok and you want to use it, we will add it to our server.
As you can well appreciate, we are not running a free board and do not want vast amounts of disc space being taken up with sig pics, attachments, etc, plus the fact that once they start to get too large, they may slow down the page loading times for some folks
