My membership level is Maestro mat I noticed this today?

The level that you earn does not reduce even after inactivity. Others may get better level but your own will not reduce. 

Yes You are right it will not change but as we are here since long time but improvement of website traffic is not improving as per our expectation.

Does this growing of our reputation depends on our activity on the website, like accumulation of points through forum posts, poll answering or are there any other means through which one can increase his level in Boddunan?

@epraneeth77 there is no other way!
