GB closed due to the owner shutting it down. They decided that rebranding from it's pedo hookup past wasn't worth the effort. As for raids.. well I've been there since 2011 and haven't been on one raid yet. Unless you count ARs for RedZone. That I'll gladly cop to. Last, I hate to burst your bubble of schadenfreude, but SLU needed to close because of having a database of nearly 2.5 MILLION posts. It had performance issues due to its sheer size. It's rebranding, not closing. The new version will be the third incarnation. It may not be your cup of tea, but viva la difference.

iirc, the software LL uses for MP was freeware. That was the deciding factor.

The best you can do is find a bento/mesh shape (and all that really matters is the face) that is similar to your current look. Make sure it's a mod shape. use your old shapes body sliders with the new 'face', then tweak the face until you get an approximation of your old system face. Bento rigging will distort system faces something fierce. But, it's that same rigging that allows for the expressions you want to have. It seems daunting, but I've had good results using a bought shape, a provided shape and a free shape with 3 different heads while keeping my original body shape.
