Welcome back PokemonMegaFan! I personally don't recognize you, but it's always great when someone comes back :D
And don't worry about life issues and doing other things, life is life and that should take priority.
As for your question, I'm not 100% sure where something like this would go. I want to say
[Trade Corner], but honestly I'm not really sure.
I might be able to help you out, but I'm a bit rusty since I took a break and I won't be available to trade until around 7pm PST.
What do you need your SID for anyways? RNG Abuse?
Anyways, I hope you find what you need; I hope you enjoy your time here :)
