You send'em. We store'em.

If too big, we'll push back and discuss other options.

If your data contains code then:

1.  Make a repo in Github for the scripts;
2.  Declare a release in Github (using the Github interface);
3. Post the Github link to SEACRAFT

After that, if ever your do a new release in Github, SEACRAFT will automatically grab a zip of that new release.
