(I saw Mexxer mention Shorena is not staff.)
Is this right way for becoming staff member?
I mean helping others and involving in solving problems..
Not exactly, members are promoted to staff when
1) The moderator for one board is needed, mostly Local boards these days and the member is known to have good decision skills and a good history(at least a neutral one)
2) Spam can't be handled by current mods(highly unlikely as there are loads of patrollers)
3) theymos thinks the person should be promoted to staff, due to high amounts of reports/accuracy or whatever his secret "formula" is.
