Converting to Drupal

I converted my SMF site to a Drupal site, I imported the posts to work with the BBCode filter, but I have the BBCode filter disabled for non administrators. What I would like to do is one of two options.

The first is to allow users to be able to edit thier posts, and asked to select a different text format available to them, filtered html, when editing any posts originally saved as BBCode.

Hello!

I was asked to convert a website to Drupal, the website is basically only HTML which I will make from scratch as alot of the content is outdated, but a very important element is not so easy to convert, and I am an absolute beginner when it comes to Drupal (advanced in HTML, PHP and SQL).

We are in the process of evaluating Drupal as a possibility to switch from Joomla.

I have three remaining issues I cannot get resolved on my own. I tried posting about one of them in the "Post Installation" forum and got little help. So, I am going to give it a go in this forum and see if some of you have solved these issues.

1) I need to have an image randomly change, in a block, each time the user clicks a link or reloads the page. I have gotten bits and pieces to this issue, and not much of any of it makes any sense. Does anyone know a good resource I can read that explains it in step-by-step detail? I am stumped.

2) I need to embed Youtube videos on the fron page of the site. While I think I have loaded all the modules to do this, the help page in the "media: Youtube" module references a lot of things I have never heard of nor seen in Drupal. Again, stumped.

3) We have a few custom PHP scripts I need to run from links and their own block as well. I have no idea where to start with this.

I'm posting this to save others some time.

When I migrated content from another CMS to Drupal 7, the em-dash (—) in the title field of many nodes turned into this: –. If this happens to you, you'll need to execute the following command from php-myadmin or the command line:

UPDATE `node` SET `title` = REPLACE(title, '–', '—')

Is there a walk through on converting Wordpress to Drupal?

Hello
I migrate my website from Drupal 6 to Drupal 7 with all the content types and cck fields. The website works fine, until I want to add new article based on content type migrated from D6.

The message after submit is:

Notice: Undefined property: stdClass::$fid w file_usage_add() (linia 650 z /includes/file.inc).
