Great idea

At the beginning of every fight with pirates they say something, isn't it possible to connect this somehow along with the boost system ?

This way you could also use it along with AI ships

I'm not sure if you would like to have your ships shields drained while they're engaging enemies.

I just installed the script the other day and I get messages on the BBS asking if I want to sell my shield to drive booster, but I haven't even bought one yet?

Ok should be fixed now. I must have totally missed that while testing the script.
