[Koha] Process to file bug

Dear all, While working on koha i found 3/4 bugs in already available options i.e. it was not working properly hence i immediately posted on bug to make aware the developers and users too. Unfortunately i have been told by one of the good developer that i am spaming ! So could you please let me know what to do if a user found many bugs? I feel every person is having limitation of time and technical capacity. Testing koha functionality and making it popular is another good contribution which can be done by library professionals easily.
