Hey there,
I use the very same website for hosting my own dioramas and stories

the site was formerly under the name synthasite which was suggested to me by JD member lehsreh when he went through a Joe diostory creation spree!
Might I make a suggestion though, what do you use to make the files into saving for PDF? Yolasite has its own built in file manager, and you can directly upload the files if they are Jpeg.
If you save each seperate page of your comic book as a Jpeg you can string them along as a full blown comic book, adding parts as you go. The way you have done it is perfectly fine, its just from last time i hosted my own stories using PDF i found users had problems (cpu browser crashes), I dunno maybe you prefer hosting this way and for me its only a suggestion. Perfectly fine if you wanna stick with it
I like the look of your site, its gotten off to a great start. website building with yola is very easy and the layout is great to use for publishing your stories with your friends. My site is here:
Urban Saboteur
As you can see I have a couple of friends site links who also use it, and i've been adding them as people join to create a nice link, lmk if you want me to add your yola site to that page and i'll do it.
If you want any help or get stuck with anything PM me and i'll see what i can do or suggest.
