You can just open one of these accounts for free and post a link on your threads like I did above, then share a download link to the file in your post and ensure it can be openly downloaded from box I suppose?
https://www.box.com/en-gb/home**Note - I think the options are for the account itself open or private rather than individual links, so I run one that people should be able to look through in full plus 2 private ones with a closed/private status for commercial stuff. Bit different to something like flickr when you upload individual files and private or not.
