my suggestions along with konichwa's(incl his too) are:
1. scrap the stupid rate system !

We shd not beg for rates from others! that's ridiculous! And ofc people rate even for silly problems also which is obnoxious
2. Start a separate place for CBSE problems, people are flooding the normal math forums with CBSE problems! that's too bad!
EDIT: I think such a place already exists but people flood the iit forums with CBSE questions

3. Nudge books shd be made private and a user shd be given the option whether to ban nudges from spammers or not!
4.Latex is also very useful and easy to learn so plz implement that
5.moderators and experts are too late in response to many problems n so we must have moderators who come online most of the time
6. Why dont you have an advanced forum and an olympiad forum too?
7. Please highlight the right answers in a thread for later referrence
8. And it should appear edited if someone has edited their post, otw they can get false credit
9. Please consider all the above very seriously
