Itch sure has a place to upload pdfs of comics, but I would say that other plattforms that specialize on webcomics are still better and more frequented. - But this is only my personal viewpoint and that might not be right. I can only say that I know quite a bunch of people reading webcomics, but noone seems to read them here. :-) --- If you tried it, do not hesitate to let me know about your experiences. :-)
