Some member signatures did not survive the migration from vBulletin to XenForo, mostly because they contained outdated pics/links. If you are a victim of a broken signature, please check it for ancient stuff and fix it. Also, many smileys did not carry over from vBulletin. It would be great if people could post what smileys they have noticed are missing. I will try to find a modern replacement for them.
Yours was destroyed during a previous update that I had nothing to do with. Sorry. This is all that's left of it: http://home.mchsi.com/~crookedfoot/My_Sigtar_Was_Too_Big_1.gif
@turok there was no avatar for you on the old site, and your signature also did not make the transition because the file was too big.
