Since the board now has a link for v5, I think if the admins wanted to add the file they could easier then it would take for you to email it. This would save you from spending time uploading the file. Plus simply uploading a file does not add it to the available downloads. They need to be added by the admins.
I won't say not to upload it, but the link is available for them as well if they chose to add it. That's your choice if you want to.
E-mailing files is good for when the file is on a local machine and not available to link to, then it works well when you submit it to the site.
