There is nothing stopping any member from customizing their signature block.

As long as it stays within the rules.

There was a fad a few years ago where someone posted a link to a program that would create fancy titles like "The Grand Upheadding Laird of Thwockmorton upon Sandy Beach the 33rd, twice removed."
Then for a while everyone was adding "Sporrano" to their username. There are only one or two of those left.

Some member put those things in their signature block. Fine. that's what Signature Blocks are for. They are a way for members to add a little something special. A quote or descriptive title if they wanted it.

But the vanity titles under the username the user can't change on their own. That can only be done by someone with admin access. First that was Hank, Then Mike1 for a while. Now that is me.

I will not give someone some vanity title all on my own, If the Staff votes a title then I will post it. But everyone will know and understand that it is not just me doing so on a whim.
