Post installation

Got a slight problem administering comments on my Drupal 4.5.1 installation.

Firstly, any comments from an anonymous user goes for moderation. However, the only way I can moderate it is if an "administrator" publishes the comment first. Is this the intended behaviour?

Hi,

I was under the impression that any authenticated user could edit a book page by default, but I can't seem to get it to work: the edit tab doesn't appear when I login as an authenticatd user. I'm able to edit my own book pages and that's all, unless I login as administrator. Is this how it works, do I have a bug, or am I missing something?

It is an mp3. Using 4.51 on Linux with Apache 1.3X and MySql . The mime types in apache seem correct and what that would have to do with it I m not sure.. Why doesnt the script read the file or what helper app isn't telling it the file is an mp3??

I'm able to add rss feeds and I can put the name of the rss feed on the right block but only the title shows up and then there is "more...". How do I make the content actually appear in the block?

What is the code for puting the current timestamp on the main page via my theme?

I'd like the rss Drupal feed produces to use something shorter as the description for an item than the item's "teaser" (which on my site is often quite long). Unfortunately, I don't know php. Can some kind soul suggest a modification (I suppose to the "Format a single RSS item" section of common.inc) that would e.g. use the first 25 words of the entry instead of the teaser as the description?
