Thanks for your feedback. Can you be more specific about exactly what kind of file you were trying to upload, it's size, and what you observed during the upload process? It would also be helpful to know what browser and operating system you're using.
I do not know if this is the right place to talk about this project but I noticed something about the layout. I was asked to submit a video connection and I gave youtube. Youtube has the disadvantage of ten minutes only videos. So I opened an account with vimeo where the video is now in full lenght. I changed the link on the projects site but noticed that the advantage was that youtube has all my other videos and there were automatically shown/listed. To give a second link, I had to change the link which was for the project itself.
What I want to point out is that it would be nice to be offered another link for personal videos related to Max.
Thanks for the feedback. You can actually submit multiple links for a project. Right below the field there are two lines that say "Separate multiple links with a comma. Ex: www.google.com, https://cycling74.com".
