great plugin, will be better if add some example

It is great plugin.
I know php, but I am just beginer for wp.
and I don’t know how to use action hook.

after search in the web and support page for this plugin.
I found the anwser.

But I see that there are other people don’t know action hook.
and some people don’t know css.

I am not ask a long detail tutorial,
but if there are some example will be better.
people can ues it more easily and you get less question in support request.

something like

css:

.logo {display: inline;}

action hook:
in which php file
use code like
function email_friends($post_ID) {
$friends = ‘bob@example.org,susie@example.org’;
mail($friends, “sally’s blog updated”,
‘I just put something on my blog: http://blog.example.com’);
return $post_ID;
}

ect ^_^

But anyway, It is a very great plugin.
Thanks a lot
