Make a text file called "customtips.txt" in the same place your wgaf.cfg and config.ini files are.
Each line is a different tip.
Beware of lines that are too long though.

oOOooo!
spiffiness!

TIP: Dont whipe back to front, and always use 2ply.

Whoa! You guys rox0rz!

But...but...but...Ray, nobody will see our tips but ourselves. Why not make a thread for tips and include the good ones in the game so the world can see them?!?!

There's a "suggested tips" thread, but it's 99% off-topic. If you have any tips you'd like to see in the loading screen, post them here. (Please refrain from suggesting "joke" tips. And keep in mind that tips based on dynamic game content probably won't be implemented.)

silentsuicide has a good one:
"Don't get angry, it's just a storm..."
Is that what you mean by game dynamics? Or do you mean something like "S16 so5 has gauss" ??

Keep an eye on your radar.

Never reverse course in a fight, always dodge at an angle.

Larger ships can pack more punch, but respond slower.

missile weapons are nice,but once you are out, you are defenseless.

Friends can help you. Enemies can hurt you. Make more friends.

A good question gets a good answer
