For purposes of say sending effects from the first unit to the second. The join would take be created when the first unit spawns the second unit. I tried to make the effects target the "My Create Unit Effect: Target" unit but that doesn't work.

Could you elaborate maybe? You're a bit too vague in what you want. If you want to just apply an effect to the created unit on creation just put your effect in the Effect - Effect - Spawn field of your Create Unit effect.

Well, more like relaying orders. I want the first unit to be able to run Issue Order effects that target the spawned unit, and the spawned unit only.

I saw the Effect - Spawn field but I don't know how it can help me, I need to run effects after that functionality has run.

Maybe I should put a dummy effect in that field and see if the effect scope or however it's called will remember the "dummy effect - target unit" unit, worth a shot.

How does the periodic effect target the created unit? All of the 'target unit of effect' stuff I've tried has failed miserably.

I could also use a reasonable trigger solution if the Unit Tag actually worked, it's always 5258259 or something.

I think he means the other way around. Have the created unit communicate with the creating unit instead of the other way around. You can use "caster" to refer back to the creating unit
