Oh yeah definitely, but don't worry if you don't, I've been here for 4 years, I've been using RPG Makers for longer, but I've never released an actual game... I don't even think I've released a demo either, just a few evented tutorials and stuff, infact, the only full game I've released was made using Game Maker, but I can't make any updates to it ever again since it's on my dead PC... but maybe I can salvage the HDD and retrieve some data, lol...
If you want to learn anything we definitely have the right forums for them, you should definitely find some help with things such as scripting, spriting and mapping, I learned most of what I know from here, lol.
