Holy wow, 2006! You must be an oldie-but-goodie! Sounds like you have a lot to readjust to but that's okay! You'll know what to do in just a matter of days (or even hours!)
Welcome back, btw! Since you're interested in Rom hacking, that section is large enough which contains many tools and tutorials you may want to read, and use. Maybe you'd like to create a team in the near future, or already have an idea that's ready to be implemented!
Have a great time and be sure to stick around! :)
