I also agree with the Web 1.0 sentiment.
Check out
this phpBB theme. It feels more current, especially the background and bottom navbar area. Having to access the UCP through a series of informal/text-based interfaces feels bad. Or even check out
this one, with responsive HTML5 design. Browsing MS from a mobile device (phone/tablet) is currently an exercise in "how to feel like it's 2006 again".
The site essentially runs itself right now, but for example, having a site presence on Twitter is a really cool idea. I wish it was used more but posting news/announcements/community engagement there is a really awesome idea. And we have a Facebook group, but that's not really doing a whole lot, and FB killed the group message thing. People only use sitechat to chat... why not play mafia games in there? Why aren't people doing it?
What about an app? What if there was a Mafia Scum mobile app that allowed users to play a live game of mafia. Nuwen and I were working on mafia.app for awhile but then she got busy, but if we had something like that, site-branded, where people could play on their phones or tablets (or even a Facebook plugin?) it would certainly increase our appeal.
All of these projects will take tons of coding and time, though, and for a site with no revenue that is purely volunteer-based, I don't think it's feasible. That's the issue. We don't want to monetize the site, and we shouldn't. But I personally think selling stuff like the t-shirts, mafia cards, even beanies or sweatshirts or TIGER ATTACK plushies, who fucking knows... that kind of stuff could be sold, and the "profits" could be used to pay someone for their efforts to get some of these larger projects done (IE, signup automation).
