Dropbox plugin? Pffft! You’re funny.
The way we do it is that Flea shared his saves folder and I simply mklink /j the particular world we play in to my own saves folder.
@InsanityFlea - I suggest perhaps that you unshare your entire saves folder, put our world folder into a shared dropbox folder, and then mklink /j back to your saves.
@iNgeon basically, every time you want to play the shared world, check if anybody in your Steam friends list is playing - if so, launch SE and check if the MP world is playing. If not, and you haven’t seen any recent changes to the DropBox folder, load up the world, or join the existing one.
Also, let me or flea know your dropbox user / email so that we can add you to the share. - This goes for anyone who wants to join us, @Vorty, @BlackSheep (who needs to get the game still).
NOTE: You don’t have to link to the dropbox shared folder - this is only if you want to play the world when nobody else is already hosting.
