Hoothooters! Can I get sum?

[Crazy Elf Boy]

Overall, sounds good. But, I have some questions to check up on.

For the "collect X individual pokemon", do they all have to be owned at the same time? Similar for "obtain all pokemon from first gen (besides legendary)". For example, if I have a Venusaur, and it started out as a bulbasaur, but do not own one now, is that ok for obtaining all first gens?

Yes

Second, will these be backtracked? for example, can i use my battle against rossy for "First hurdle".

Yes

For, round robin, is there a list of all currently active members? (This is the one I have the biggest beef with, since "currently active" is hard to define.)

Hell if I know. Also Blade you are a gym leader so you have no cause to complain.
