Yeah I was pretty worried. My hope is that we (and when I say we I mean everyone) can move on from what happened and eventually forget and continue making music like if it didn't happen.
Seeing how it ended well, I guess we will probably get more and more active in the future, unless a massive amount of active users decided to move on to other things, but I doubt this will happen considering a lot of users have been active the entire time.
I think it will continue to grow because even if we risen in google rankings we are still low and we might continue to rise if more and more people put the link to the site in their signatures on other sites or forums and their personal site or submit it to link databases. Also, it seems that retro gaming has become quite popular with the years. People are nostalgic and miss the games from yesterday. Until the recent years only the Atari, SMS and NES were considered as retro gaming, but now the SNES is to and I even heard people talking about PS1 games as "Retro games". Because the PS1 is aging eventually it might be considered as a retro console too, so people will rediscover the old games on them, and because MTVMG is on it, this might interest them and they will seek for a copy legally or... erm... illegally. Seeing how Mario Paint arisen from the death in the past years (look at how many mario paint composing videos there are on youtube and they even now have a forum with 16000 posts http://mariopaintcomposer.proboards56.com/index.cgi
and there's even a Bootleg PC version of the SNES composer part of the game) and grew in popularity 16-18 years after its release, this might actually happens with MTVMG series if people rediscovers about the PS1 music programs. Like with Mario Paint composer, people will find it "cool" to make music with MTVMG series and seek for a place exclusively related to it.
The downside with that is that there are big chances that we would get weird members including a lot of 4chan/b/-style peoples if you get what I mean, and there might be some other MTVMG sites starting up by admins not aware we exist yet so there might be competition (not that it's that bad, though, just that some losers might hate us and troll our board), but we will sure get a whole lot of activity increases if this have to happen.
