Well, the numbers can be decided by moderator himself. He might have the data of Average No. of IMG trains created by a member monthly/weekly or whatever helps. The numbers I mentioned is just as an example.
If you have a quota of creating 10 IMG trains a month and a members utilize the quota within 10 days, then to create more IMG trains, please flag/review other members x number of IMG creation. Keeping the quota around 5 to 10 for a member knowing that it will eventually exhaust for many within 10-15 days will lead to members flagging/reviewing IMG Trains to increase the quota for the month.
please wait...Translate to EnglishSo, the guy running the show can set the numbers himself. He probably knows the Average No. of IMG trains made by a member each month/week or whatever works. The numbers I mentioned were just for your reference.
If you're supposed to make 10 IMG trains a month and someone finishes the quota in 10 days, then to make more, just report/review other members that haven't reached their limit yet. Keeping the quota between 5 to 10 for each member, knowing it might run out for many in 10-15 days, will encourage members to report/review IMG trains to bump up the quota for the month.
