@yarikoptic I'd like to work on this item on Friday. Probably something I'm not forgetting, but can't seem to debug at the moment. Thanks in advance!

[yarikoptic]

git remote add --fetch rolando-exchange heejung@rolando.cns.dartmouth.edu:/inbox/BIDS/Wager/Wager/1076_spacetop.git

and then push to rolando-exchange not rolando

[yarikoptic]

did you draw that figure we sketched up? here is a possible sketch you can improve further using mermaid and https://mermaid.live/edit or alike
