Single post in Place to catch pokemon? Choose the pokemon battle moves?

Absolutely not. The shelter is for people to quickly find eggs and Pokémon to hatch/level up/etc. If something like this was implemented, people would spend more time trying to catch the Pokémon they're looking for and less time doing what the site is based around - clicking, forums, hatching eggs, etc. Yes, this is a Pokémon site. But that doesn't mean all Pokémon sites have to follow any of the games.
