Why you want to bring new users to this forum? that will be like fighting against the current, and you know what happen to those who cant fight the current...
This forum should remain how it is, about BTC, maybe some of the subforums can be removed or can be disabled, read only mode, like the altcoin forum because no one use it anymore.
And we should have a Bitcointalk day, that can be the the same day as pizza day, so everybody once a year, will remember that Bitcointalk was the most popular forum about crypto and died, and we can celebrate having one minute of silence because the forum is dead and nobody use it anymore.
