Hey all,
Was trying to create a shared Google Drive where we could all upload our pictures from the event, but apparently it lacks that feature. Google Photos seems to though, so I have created a random new Google account and added a folder that allows shared uploads at their original quality (15GB free). I've slapped my pictures there and can add anyone who wants to upload any more. Just give me a shout via PM & I can throw you the link.
Not the best way to do it, but Dropbox's free plan only allows 2GB which I don't think will be enough.
