I was pleased to see that there'll be an extra problem coming out this weekend (I have plenty of time now since my exams are over). It also reminded me that there appears to be a small bug in he email system since it sends out two emails (one for each problem). Ideally it'd be nice to receive just one email noting that problems 249 and 250 were coming out.
This may, or may not, be a small change but it's not too big a deal if it's not possible.
Looking forwards to problems 249 and 250,
