The signature generator is back now, but unfortunately in order to get it back and to please our web host we had to take away the ability for them to update on the fly. Updating them on the fly uses a lot of system resources (even with caching) and at the time our account was suspended we had over 200 signatures being created at once, so you can see why we were shut down. Hopefully this solution will please everyone, and not cause any more trouble with our hosting service. You can still update your signature after you have created it by using the generator again.
If you still want to have people see your latest avatar/lot information, there is a link provided to your avatar/lot profile page when you create the signature.
It’s quite disappointing it didn't work out the way I had wanted, but I hope you all still find them useful.
