I'm pretty new here and don't exactly know what has and hasn't been claimed as far as 3D modeling goes. Are there spreadsheets anywhere that have a 'whos-claimed-what' kind of thing?
If I've missed an obvious thing anywhere that might answer my question, sorry in advance. Thanks.

this shows what modeling jobs are claimed and which ones are still open.
Happy Holidays!
