Reading Quran alone, in mehfil, for genral blessing, for eisaal-e-sawaab is perfectly all right and the act is worthy of sawaab ..
I am not sure why we are having such lengthy discussions here.
I agree with you , those who think it is perfectly all right they can go to those mahfils and get sawab and do an esal a sawab.
Those who think it is not , they can read it alone and earn all the sawaab.
