My forum has been up and running for about 15 years. Some members are proud of the fact that they have been members since day one. I'm constantly asked by people what their registration/member number is. I know how to find it, profile/address bar/far right end. I would like to add that number to their postbit though, just below their name. I tried to ask this question on the VBulletin.org forum but the forum there seems to be down.

Can anybody help?
