I'd go ahead and sign up for anything you're potentially interested in now. If you somehow get randomly drawn for multiple teams, we'll probably just end up asking you to pick where your priorities lay and go from there!

Something to keep in mind is that this is definitely one of those instances where resolving distractions such as the door systems and gravity field issues will make other things (life, getting to the transport room, recon etc) easier on everyone, so you may want to consider which lists are currently short staffed when looking at what to put your name in for.
