Well, I'd certainly love it if you could link to those plugins, because I did some searching and couldn't find anything. Maybe I didn't look hard enough. Anything with leaderboards, social features, multiplayer, etc.
What I'm asking is, what process would you follow to create a social MMO. In regards to the tools I mentioned in my OP, I would like to know how to create a plugin so I can make them work with Construct2, as they could be very useful in creating that type of game.
Thanks, you're awesome. ;-)
