No, he means you must:
1) Link (
like this) all the plugins in the main post, to the corresponding thread in this forum.
or
2) Add all source codes from all plugins containing in this post (through a single zip or through attachment), if you haven't some source code from a plugin, so remove it from the download, since is against the license and the forum rules, so it can be approved.
But, as he said, this post looks more to a tutorial than a plugin.
