Here are a few things worth mentioning;
Positives:
1: Active during the "Night" period where most staff members usually aren't on
2: Helpful and kind to others on the server
Negatives:
1: Some inconsistency with your two weeks of active play time
2: Recent warnings
3: Application could of received some more time and effort put into it
Honestly, I don't have much of a problem with you becoming a member of staff, but I do believe you should reapply next week, that way you can work on all three of the negatives I've listed, as they are rather simple ones you could sort out in no time!
