RTNS 24, The 32nd International Conference on Real-Time Networks and Systems, which has three deadlines over the year, with accept and reject decisions, as usual, but also “Major Revision: the paper may be re-submitted in the second or third round and will be re-evaluated by the same reviewers.”
I find this a nice way to support those not familiar which specific writing styles or requirements for papers. Instead of a rejection and another attempt, with possibly different criteria, this allows to take reviewer comments, need for clarification etc into account and try again at the same conference within reasonable time.
