For those of you who had trouble with wormholes, I found a really easy
answer. I made this simple tutorial that shows what you need to do to
make a stable connection.
1. First, make a system (duh). Make your wormholes. For now,
just place it out of the way so you can see your connection line
(Phase Lane) clearly.

2. Hover your mouse so its DIRECTLY over the line, and press like
your going to select it. And it will:

3. The box to the left changes to the connection properties. Go down
to where it says Connection Type. On the drop menu, change from
Phase Lane to Wormhole. If you did everything right, it should look
like this:

And there ya have it. Simple wormholes in Galaxy Forge without editing the
.galaxy file. I hope this helps people. I know I was having my brain explode
trying to figure it out. Anyways, Enjoy wormholes
