A s2member add-on that allows you to upload a file to the s2member-files/ secure directory and automatically insert a link into your post.
it doesn't work. maybe because of S2member updates. waiting for repaired version.
The files do not upload to the secure s2member directory (app_data) but to the into the root of the s2member plugin.
And the link generated to the file does not point to the correct directory, but to the root directory of the WP installation.
It looks like these issues could be corrected in the php code, but I don't know how to fix this and hope the plugin author will fix.
