I no longer RNG, but I guess teaching someone/resuming RNG for a bit wouldn't hurt
What do you need help with? What RNG type are you trying to learn on White since I can only RNG on White/Black x3
I can teach flawlessness/shininess/HP 70 in eggs, and event wondercard RNG flawless/HP 70.
For 4th gen HG/SS I can only do gamecorner Pokemon/non-shiny stationary pokemon
On Platinum/Diamond/Pearl, I know shininess RNG for eggs but not IV manipulation.
What are you having trouble with? Maybe I can explain better than Smogon xD Smogon's RNG guide is sooooo hard for any beginner xD
