I have found large amount of solutions in forum of ext.net responses
But i found 10x times more forum thread which did not help me solve my problem.

I have sugguestion.
make authenticated users be able to write down (some sort of hastag on forum threads) related to solved problem,
so unsolved or unused threads would sink down, while most concurent problems would be floating with new thumbs up or votes or whatever system to be implemented

Resumed: I wish for voting system to rate helpfull threads and identify problem i was looking, that was solved by visitng that thread.
