I have finally decided to start the forum using phpbb after making a lot of research and analysis.
I am now confronted with one major issue. I know that while having it mandatory for usesr to submit their email addresses while registering in forum has many many advantages in terms of better control, notification and so and on and so forth.
But still I would like to have a forum where people can register at forum powered by Phpbb without making it compulsory to have their email address submitted.
I am unable to implement this. Can anyone suggest what changes need to be done in settings or codes of phpbb so that i can have optional emails system at least for some of members.
