The best part is that it's free! I can easily create all my fonts, from scratch or even with other people text/fonts which i have created before using this software in previous versions of Adobe Creative Suite (CS).
You don't need any training at least not as much compared to some paid products out there like TypeTool etc., but you also cannot edit existing files if they are already present within CS suite such as AI PSD file format - so be careful how many times do your work require editing an original source document since most likely after one time will make changes difficult afterwards without having access back into those documents again by opening them up through File > Open command prompt window option. It would definitely help when creating new projects where we want something different than what comes defaultly included inside our programs' libraries because nothing looks good unless its unique looking otherwise everyone else has their own way.
