If you don't want a Pokemon in your party, you can put it in a PC box in any given Pokemon Center. If you just don't want the Pokemon, then
1. Place it in a box
2. Select it
3. Under its options hit release
and the Pokemon will be released

i have had no experiences with it and i do it a lot on platinum
the move deleter in canalave city :) =)
I'm not completely shure, but i don't think you can.
In order to delete a save file in Platinum, start your Platinum game and go into the title screen aka the screen where it shows Giratina at and where it says "Press Start." Next hold down the B button, the Select button and Up on the D-Pad all at the same time, it'll ask you if you want to delete the current file then.
To delete your account on Pokemon Platinum you need to press B and Up while you are on the main menu at the intro of the game.
