This just a spun of the moment, though

Every ppl who suggest here can have a credit for their part of rrl improvements.
My suggestion is :

  • Add a admin approve button on ppl's thread

  • Change the color of thread being approve the rest of nornal threads

Even though its a pointless of  to add but by giving acknowledgement to ppls also give us a sense of achievement even though a little part on rrl . 
Sometimes it mptivates us also
