[Feature] - repeated message to remember submitting/abandoning plots

[straussi]

We perceive that on the one hand there exist many finished plots that are unsubmitted and on the other hand many not finished plots, although the builders are talented and build very well regularly.
In our staff team we decided the best fitting solution to this problem would be a message in the chat that remembers the builders every 15 (10, 20, ... the number of minutes is arbitrary) minutes to submit finished plots with /p submit and to abandon plots someone does not like via /p abandon.
If you could implement this feature or another solution to the problem, this would be very helpful.
