@Andreas Nurbo -

Why is it so hard to go with all credit links must be optional standpoint?

I think Marks answer is generally the way he and Matt both feel about the guideline with themes and plugins. In this matter, I think you'll have to realize that this is the way it's going to be, despite your best arguments against it. While I still don't like the fact that I can't control the behaviour of revisions from the back-end of WordPress, I've given up my argument for it. Somethings in the world of WordPress are just going to be the way they are. This is one of those issues.

Tell you what though, I am going to ping Matt Mullenweg and point him to your comment and we'll see if he gives his thoughts on why their is a difference between the two.

@RJ - I like your line of thought. You raise a point that I thought about after I published the post and that was the model of paying to remove the credits. I think this is one of the dumbest things worth paying for. It's not like I want to remove the credits, I just want credits to be where they ought to be and only on the front-end of my website when I specify them to be.

@Justin Tadlock - Justin, you're a shining example of someone who 'Gets It'. Theme Hybrid is such a nice piece of work that I've opted to keep the link in the footer. What good is thousands of links with no substance? I think it would be much better if I took a plugin and wrote a review or found a plugin that solved a problem I had and then tell the world through a blog post. Choice is good.

@Miroslav Glavic - I like you're linking policy. As I mentioned to Justin. There is a big difference between just a link and a link with substance. I don't like the idea of a plugin created credits page either unless it's created by me. A good plugin for this roll is called WP-PluginsUsed by Lester Chan. Let's not forget that their is an annual tradition now of giving thanks to plugin authors started by Matt last year. I totally forgot this year though.

@Latz - Is your plugin in the repository? If so, wouldn't it be better to provide support for it on it's own section of the WP.org forum? Usually, the WordPress version and plugin version info is provided up front in a support post.

@Ryan - Why is the extra credit needed? The way I see it, the plugin repository and the plugin management pages provide plenty of opportunity to credit the plugin author. Any credit delivered to that plugin or author beyond those standard means I consider to be extra credit. That extra credit should be given by me, not by the plugin or theme author.

@Chip Bennett - There are already numerous plugins available that give end users the chance to create a dedicated page or post which lists all plugins in use. In fact, the one I linked to by Lester Chan is my favorite because it pretty much takes the same information from my plugin management page and puts it into a post via shortcode. Therefor, this is not something that should be addressed in core since standard credits are already handled by the core.
