Same here. Tried to make a nice Full Member signature myself, but I can't use them. Works on Chrome, but completely screws up or looks bad on others:

Here an outtake/screenshot:

It follows all the rules, but I couldn't use it, because it doesn't work across most platforms. I'd be fine if it would be 80-85%+ I guess, but it it's not even close. The admin did a great job when he enforced the new rules. Lower Member classes are pretty restricive now. No big signatures for them.
