Sometimes I don't know until I open the box. I wish I had the information sooner, but generally the donors don't really know what they're sending until they pack it, or they're too busy to provide the info.
Generally it takes me a few hours friday night, and throughout the day on saturday to get everything in, having to locate pictures, etc. Some of the stuff might be in the tanks before its in MGA, so your best bet is to stop by and take a look if you're around.
