Ahhhh, alright. Almost got where I was aiming for. Almost. That added the text automatically, and that is perfect, but I am having an issue.
Ok, so the main reason I needed this whole extra feature was because I also have a mobile version of my site, and I am looking for a way to automatically add a signature to the comment that comes from the mobile version of the site. So I added the code to the functions.php of the mobile plugin, and that added the text to the bottom, and it added it to all of the comments automatically. The issue I had was that it at first showed up only when looked at from the mobile version of the site. It did not show up on the regular site, that is not the mobile version.
Second thing I tried was adding it to the main functions.php file of the plugin. The plugin has two, one for the master settings of the plugin, and another functions.php for the theme being used. So I added it to the master functions.php file of the plugin and this time it put the signature on all of the comments. Again, this is half way, because not all of the comments were made from the mobile site.
So this got me to almost where I needed to be. The thing I would require is that the text gets added automatically after the the comment is submitted from the mobile version of the site, then show that it was made from the mobile version of the site on both the mobile version, as well as the regular site.
My logic for getting this would be to add something somehow to the functions.php file, or some other file, of the mobile theme. This way when a comment is made from the mobile version of the site, the extra text would be added to the comment, but it would display the comment regularly in both the mobile version as well as the full version of the site. The text gets added only if the comment is made using the mobile plugins comment.php file, or whatever file I need to modify.
If that whole ramble of mine makes much sense. Thank you very much for your work though, it started me off in a right direction and got me a whole lot closer.
