I am trying to customize Drupal for my community website and I have a question about extending the functionality of the blog module. I have successfully added a hook into the create blog entry form that I am calling "Targeted Publishing". Basically this lets the user choose any of the existing nodes of a particular content type and have their blog posting show up there, allowing for product specific blog posts. I don't really have a handle around how Drupal works yet, but while the form displays the fields, I am not sure what happens to them when they are submitted.

First of all, sorry for my terrible english, but I hope that you help me :)

I want to use dashboard as front page. But now I only have a link to my dashboard on frontpage (and "Dashboards have no teaser, sorry."), though I have checked "promote to front page". In settings of site I didn't find function 'use this page as front'...

Hi I'm interested to know of the current status of the 'stores' module where every user can have their own store? I have just downloaded the ecommerce module for 4.7 but I did not see any stores module to enable (unlike 4.6). What can the stores module do now? Specifically how does the stores module work from a customer's point of view: do they purchase using a central payments account.

Sorry if I'm too general, but I'm trying to evaluate this module and am finding it hard to find suitable documentation for it.

I thought this would be easy, but can't figure it out. In a module how can I find the absolute path to the drupal directory? I can find the path to the module (both relative to drupal basepath and absolute), but not to drupal itself.
