Yes, he is still closely involved with the project.
Is there any proof of this or are you just guessing? I'm new to MAX so I don't know who anyone here is but you don't look like the dev. Are you a max coin insider, perhaps?
It would be nice to get some sort of official confirmation from the devs here stating that max is still very much involved in MaxCoin. That would be a big deal to a lot of new investors.
Cheers!
