As has been said over and over again...
The addons can allow almost any functionality. If they want to allow you to choose any skin you like, then thats possible.

One mod can do an entire game mode. What people mean by having two mods is that you might want one mod that does stats, or admin control, which can run along side the game-mode. This isn't currently possible, but we'll look into it.

Ok, doing this would be more suitable for some game-modes than others... So it'd be a game-mode thing. As you can download 100% complete saved games off the net, I don't see it being particularily interesting in that respect...

Well we have up to 600 people playing at a time... we expect that blue will increase this, so yes we could have larger servers. Whether we will is another matter.

Bullets are pefectly sync'd, but we've left in the auto-aiming because that reduces the appearance of lag to a certain extent. If we feel that removing auto-aiming would be beneficial, we may. As for molotovs/grenades, these now sync propperly and will land in the same position for all players.

No, you can't be a beta tester... We'll release info about beta testing nearer the release.
As for the other suggestions, how would blue know which saved game? And how would that be fair? I've never seen a multiplayer game that bases itself on how well the player did in singleplayer...

It'd be possible for an addon to be created that'd save scores, but I think by default they'd be lost if you crashed (like every other on-line game).
