Drupal 4.7.x

I have downloaded tinymce for 4.7 in the module section but it seems the file is about empty , where to download the good file ?

i'm using drupal "4.7 beta 4" i don't know what but it seems Drupal has forgot my password from the database and always prompt me with "Sorry. Unrecognized username or password. Have you forgotten your password?" even i'm so sure the password i'm entered is correct.

I've search this forum and i found a way which is changing the password directly from the database by using SQL query. I did it within the "phpmyadmin" and then turn back to the drupal by keyin the corect user id + password again, but still failed with the above prompted message again...

it's a well-designed theme. how come not available here?

I have some blocks that make fairly intensive calls on the database with several taxonomy get tree and sorting calls etc. These calls are noticably slowing Drupal down. However, the taxonomies in question are only updated once a week or so. How can I go about caching these blocks? I guess there is no way within drupal to ask it to cache certain blocks, but not others?

How can I get the node ID, that will be post after the filter processing $text ,in a filter module?

Thanks a lot.

I know there is big discussion about meta tags... but is there way to add meta tags and description to 4.7?
