Module development and code questions

I need a module that adds a "subscribe to this blog" block on each blog. Anybody, including anonymous visitors, should be able to enter an email address to subscribe, and at the end of every day, if the blog has new content, an email would be sent to all the subscribers, listing the titles of the new entries and a link to the blog. In the email, it should also provide a link for the user to unsubscribe.

I found the Flexinode module to be pretty incredible in its ability to create sortable tables of data and also to display lists. I have created a flexinode for stock deals that I'm tracking. I would love to be able to enable my users to view this information in the tabular view and sort by the current change in stock price. The stockapi module looks like it is perfect for getting the latest stock ticker info.

I followed the directions at http://drupal.org/node/18429 but I get table not found errors. Clearly, Drupal is not seeing the database I set in db_set_active();

Does that page still apply to 4.7?

has anyone gotten aggregator2 working on 4.7?

Can someone help me debug a module I'm writing? The check_output() calls in the function that formats the output (starting on line 263) doesn't seem to be doing anything. I don't get urls autoconverted or linebreaks, just plain text.
