sorry if this seems silly but i sat through the tutorials and im sure it never mentioned this.
im currently stuck with one capital ship and a small amount of fighters as i cant work out how to progress through the ranks. it asks for certain numbers of research buildings (which i have) but then asks for "1 point in X" which i cannot find anywhere in the research selections.
When you click on something you don't have the research for it normally highlights it in the research tree when you open it up again.

. Yes, I kinda feel like the head of a big corp in Eve directing all my fleets into battle, but none of the waiting months/years to get all the cool skills 

awaits kreeeeee
