I've been playing around single-user (which is manageable, at least for diving and surfacing!): filling the ballast tanks, emptying them and playing with the negative tank.

I now understand that having the ballast tank full (main ballast) leaves me with neutral bouyancy and using movement + planes allows me to use that to move up and down in the water column. The negative tank was a puzzle until I played around with it. Really good fun (what a teaching tool!).

One thing I cannot find is where one set's the lobby name - I've tried googling but to no avail.

Currently you cannot set the lobby name. It's your name's lobby.

Ah, thanks

Ive been trying the same and am really enjoying just using the different parts of the diving apparatus - but cannot set neutral buoyancy, i open the two vents front and rear but start sinking straight away. As far as I understood - when these are full this should leave me at neutral and as you say, movement plus the planes shoudl let me slip below the surface when I want to. Thats not the case - how did you do it Bob?

You are starting to sink immediately because after you flood the main ballast tanks you have negative buoyancy as the negative tank is also filled. Once you are submerged you should empty the negative. As soon as possible, as it takes quite a bit of air once you get deeper. But not entirely empty it! To get properly neutrally buoyant at periscope depth you should leave 0.05 m^3 (or 1 halve tick) in the negative tank.

At deeper levels you may need to empty it totally and empty the main ballast tanks also a bit to become lighter and compensate for your more compressed volume. How much I don't know yet.

Thats the job - submerged nicely now

slipped below the surface without opening main ballast tanks .. all I did was fill the water tank to full and she started diving,, main ballast tanks? anyone try this?

Sorry AJ not sure exactly what you did here. You cannot fill the main ballast tanks without opening the valves, and the negative tank starts in the game already full. Rgds.
