Whoa, four years now?! Impressive. xD; It's about time you got to posting here! Better late than never, right? :) Welcome to PC, Beckiie!
Good luck with your channel, I'm sure it'll do well if you continue to make updates and try your best! Glad to see you're utilizing your signature for that already since that's probably the best place to show off your videos. Like Chibi Pelippers said, you're always able to post your LPs in our Let's Play subforum so that's a possible option anytime; glad you'll be looking into that. And whee, it's amazing to hear you're excited about being here as well, haha. People like that get the best experience out of the forum and I'm sure you'll be making a whole lot of friends along the way. :D; You've already met some really great members that'll surely be around if you ever need it, so there's that, right? Our members are generally super friendly and especially helpful, so if you need anything, don't hesitate to ask!
ROM hacking is a great thing to start with given its popularity here and I do hope you'll end up publishing an awesome game for us to try sometime. I always recommend people look at the
Help Recruitment thread if you're looking for some assistance along the way, though unfortunately it might take a little bit for a reply since members are busy. There are a hefty bit of tools and resources for the aspiring hacker there though, so if you're looking for some neat things to add to your game then you've come to the right forum. What hacks have you played? My personal favorites are Shiny Gold and Prism, though others like Flora Sky and Ruby Destiny are awesome, too.
Be sure to look around other parts of the forum as well! There's a looot to do here, from battling and trading to discussing video games and talking about music. PC is a really diverse place and we have thousands of active members. We love you and want you to feel at home here. :) See you around!
