[@Hylozoist] Hello~ Welcome and happy to have you.

To answer your most important question there is room for more players. We are always in need of pokemon. 

Which type of pokemon do we need? Its a pretty free choice, and it depends on the trainers in this game. Ergo Trainers are: [@Bright_Ops](has 2 pokemon)[@Raijinslayer](has 3 pokemon + 2npc)[@Saltwater Thief](has 2 pokemon) and Me(has 3 pokemon). 
My opinion on this is the game needs a water type for all those fire and the ground types that are around. Plus surf. Plus Rasa needs a swimming buddy even if that isnt her own pokemon. XP Again all types are great.

Now for when it is best to get involved?
At the moment there is a bit of a problem as they are two groups. One is on day one, and a few are on day two. [@Holy Soldier] Plans for everyone to rejoin as one group on day two and then as one group move forward. I would recommend you join a trainer before we all meet up. Thougth you should talk out with your future trainer how you want to be caught.

I hope this helped answering it. Anything else you wonder about?
