Drupal 7.x

How to have field that sends email from within Drupal?

Say you create a content type with the field email address, so when creating content, you input the email address.

Then when you view the content item, there would be a link with the email on it, but instead of going to Gmail or OS email client, it goes to a form and I can send the email to contact direclty, like CIVI crm activities behavior.

I want the sending and receiving of emails stored in Drupal, without need for outside webmail or email client.

Can't add images so here is the link to image:

I need to create a system to let my users tag content for their own use. Essentially setting up a "favorites" or "bookmark" system.  

Theyll never see the actual nodes, just the content presented in a Views table. 

I tried adding a taxonomy field to the content type, using a single "save" tag. The problem there is that the field is only available to the node author. End users can’t see it until the tag has been added by the author, defeating the whole purpose. 

I cannot find any documentation with explains the $attributes variable which appears in a line in node.tpl.php.

<div id="node-<?php print $node->nid; ?>" class="<?php print $classes; ?> clearfix"<?php print $attributes; ?>

I have found the function in template.php which creates $classes but nothing for $attributes.  I'd be interested to know where this variable is created and what part of the page content it generates.  Any pointers to documentation would be good. Thanks.

I am developing a pretty comprehensive directory with a typical country -> state -> county -> city hierarchy using taxonomy. That is pretty straight forward, but creating the navigation structure for it is alluding me.

My initial thought and ideal solution was to use either Hierarchical Select or SHS to allow the user to drill down to the appropriate level, click submit, and have the system redirect them to the corresponding taxonomy page.

Using Drupal 7.XX, I'm trying to categorize and group content based on taxonomy terms, could able to achieve categorization using view but i want to know how i can group this content. Below is the scenario: I want to expose below option to user so that he can view content group by either "region" or "business Unit".

Group By -- Region
-- Business Unit

I know this can be achieved using view but i'm not able to thought process the actual implementation. Let me know for more information needed. Appreciate your help.
