Hey there, Nico! Welcome to the PokéCommunity! :D
You seem to be enjoying yourself. That's good. And your username is pretty neat, because I think Excadrill is awesome! It might have been banished to Ubers in the competitive scene but it's still a great Pokémon to like. You might as well enjoy it here because everyone pretty much has as huge a background with Pokémon as you. Hey maybe you'll meet other Excadrill fans around because I know a few here and there. Just get into the topics and post around, note that we have bustling discussions for fourth and fifth generation games so go check those out, maybe share your fun experiences in BW~ Oh and we also have a Trade Corner if you wish to make a few trades with fellow members. By then you should have a gist of what to do and not to do, and I trust you can check both forum-wide and a few other unique rules of the section.
All that can be pretty overwhelming. No worries though, you're free to ask for help from approachable members, especially the ones donning shiny moderator badges below their colored username. They don't bite, and neither do we regular joes. So as you settle down, I really hope you enjoy it here. We're always glad to have new people aboard, and I'm sure you'll enjoy meeting new friends here. See you around!
