Module development and code questions

I'm trying to get Narkoba's podcast module to work, and am having some wierd validation and usage issues.

I have one primary site using Drupal , and one subdomain set up as a a Drupal multisite.

Everything looks fine within the site, but I have 2 problems.

1. The sub-domain site podcast feed (http://astronomy.podcastformat.com/darkmatters) validates OK at http://www.feedvalidator.org/ but when you look at the feed, it is devoid of any episode information (ie RSS items).

2. I set up exactly the same thing on my primary site with a feed of http://podcastformat.com/podcast/feed/7 and when you look at the site or the feed (by browsing the link) it looks like a perfectly valid feed with episode tags, itunes tags etc etc, but when you throw it into feedvalidator, it reports all sorts of errors and shows half of the tags as being empty (beginning with the title tag).

Even more frustrating, when I throw in the feed link at Narkoba's demo site http://www.narkoba.be/narkoba/?q=podcast/feed/180 it validates OK, but when I compare that feed and my feed in the browser, the tags all look exactly the same - actually mine even show more tags with info in than his does.

So, the first problem is stopping me using my subdomain for podcasts, and the second problem is stoppping me using anything for podcasts!

If anyone can shed a light on any of this, aprticularly why a browser view looks complete but the feedvalidator view looks incomplete, I'd greatly appreciate it.

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?

Hello

I have a customer who wants to use Macromedia Contribute to maintain content. The site structure is predefined, it's really just existing pages they might want to change, and the staff know and use Contribute.

A couple of features of Contribute are: you can secure a single folder for users to access and the user can be limited to the css files referred to by these document they are editing. FWIW, it also hides head/php/javascript from the user,
