YES YOU CAN! belive in yourself, all you have to do is download some files to your computer. then use a program called: cuteFTP, or flashFXP or whatever you like to upload it to your site. just like you upload your content. then just go to whatever place you installed it too like: www.yoursite.com/whereyouUPload
with internet Explorer or whatever your browser is and there should be an install file there, click it. fill out a SIMPLE form and your done. all fantstico does is fill out forms, and you still have to fill out fantsticos form so its kinda the same.
you can do it, its OK.
if you need ANY help, post here.
