37	+ = "Sign me up" checkbox =
38	+ One of the things NSU does is adding a "Sign me up to your newsletter checkbox" to your comment and registration forms. Most visitors who care to comment are willing to subscribe to your newsletter too.
39	+ Signing up to your newsletter is as easy as ticking a checkbox!
40	+
41	+ = Sign-up forms =
42	+ Another strength of NSU is the ability to create sign-up forms and easily embed those in multiple places. Newsletter Sign-Up comes with a sign-up form widget, a shortcode to use in your posts and/or pages and a function call
43	+ to use in your template files. You can even choose to redirect the visitor to a certain page after signing-up, offering them exclusive content or a "thank you for signing up" message.
44	+
45	+ = Using MailChimp or YMLP? Use their API's! =
46	+ If you're using MailChimp or YMLP then you're in luck. Configuring is as easy as providing your API credentials so that Newsletter Sign-Up can work with the API of your newsletter provider.
47	+
48	+ = Customizable =
49	+ All generated forms come with common CSS classes and unique CSS identifiers so that you can easily style them to your likings.
50	+
51	+ = Easy to setup =
52	+ Configuring Newsletter Sign-Up has been made as easy as possible. With the Configuration Extractor that comes with Newsletter Sign-Up all you have to is provide your sign-up form HTML code, the configuration extractor
53	+ tool will then analyze it and try to extract the right values for you.
54	+
55	+
56	+ == Installation ==
57	+
58	+ 1. Upload the contents of newsletter-sign-up.zip to your plugins directory.
59	+ 1. Activate the plugin
60	+ 1. Specify your newsletter service settings. For more info head over to: [How to configure Newsletter Sign-Up](http://dannyvankooten.com/wordpress-plugins/newsletter-sign-up/)
61	+ 1. That's all. Watch your list grow!
62	+ 1. Optional: Install [WYSIWYG Widgets](http://dannyvankooten.com/wordpress-plugins/wysiwyg-widgets/) if you want to be able to easily edit the widget's form text.
63	+
64	+ == Frequently Asked Questions ==
65	+
66	+ = What does this plugin do? =
67	+
68	+ This plugin adds various way to your WP blog for visitors to subscribe to your third party newsletter service. What once started out as a simple 'Sign me up to your newsletter' checkbox at your comment form is now a
69	+ superb e-mail address gatherer. This plugin respects double opt-in rules, it's all legit.
70	+
71	+ = What is the shortcode to embed a sign-up form in my posts? =
72	+
73	+ Its `[newsletter-sign-up-form]`.
74	+
75	+ = Why does the checkbox not show up? =
76	+
77	+ You're theme probably does not support the comment hook this plugin uses to add the checkbox to your comment form. You can manually place the checkbox
78	+ by calling `<?php if(function_exists('nsu_checkbox')) nsu_checkbox(); ?>` inside the form tags of your comment form. Usually this file can be found in your theme folder as `comments.php`.
79	+
80	+ = Where can I get the form action of my sign-up form? =
81	+
82	+ Look at the source code of your sign-up form and check for `<form action="http://www.yourmailinglist.com/signup?a=asd123"`....
83	+ The action attribute is what you need here.
84	+
85	+ = Where can I get the email identifier of my sign-up form? =
86	+
87	+ Take a look at the source code of your sign-up form and look for the input field that holds the email address. You'll need the NAME attribute of this input field, eg: `<input type="text" name="emailid"....` (in this case emailid is what you need)
88	+
89	+ = Can I let my users subscribe with their name too? =
90	+
91	+ Yes, it's possible. Just provide your name identifier (finding it is much like the email identifier) and the plugin will try to submit the user's name along with the request.
92	+
93	+ = Can I also show a checkbox at the BuddyPress sign-up form? =
94	+
95	+ Yes.
96	+
97	+ = Can I show a sign-up form by calling a function in my template files? =
98	+
99	+ Yes, use the following code snippet in your theme files to embed a sign-up form: `if(function_exists('nsu_signup_form')) nsu_signup_form();`
100	+
