Gengar is an awesome Pokémon. But yes, hey there, Gengar! You've been here before? Three years ago eh? That's pretty interesting. Do you remember your old account? I mean if you've been here before, then that's gonna help you in getting used to this place a lot more, I'd hope. Of course, things might have changed here and there. I'd imagine a lot of things have changed, actually; add onto that the fact that you're still getting used to the site even now. So you'll probably do a lot better around here if you read the
FAQ and the
Rules for reference. You could also approach fellow members and staff if you have a burning question you want to ask! It's not that difficult to get started, really. I'm sure you'll do great.
Still, you're gonna have to be as active as you can! That's one of the first stumbling blocks that new users tend to face. Lacking activity is a horrible situation to put yourself in, and I can attest to that. The biggest thing that it does is that you wouldn't be able to experience the forum to its fullest. And it's a real pity, because this forum just really runs on fun, so you should really just have the most fun while you're in here.
As for the generic message bit, it's a pretty quirky thing to put in your intro and it isn't as generic as you'd think. It doesn't save you from being a total stranger though! XD; So tell us more about yourself! Interests, favorite things, hobbies, career choices, even just Pokémon related stuff if you'd rather stay true to the forum's theme. Just speak out. I mean really, it's free! What more could you ask for? ;D
But yeah, I hope that you at least pick a thing or two from what I've said. Just enjoy this place as much as you can, buddy. See you around.
