Post installation

Does anyone know if when book pages are edited by multiple people at once if there's a warning or if someone's editing a page, no one else can?

Hi people,
I want to set up a site for bloggers. I've played around with the taxanomy module - which is great - HOWEVER, when adding free tags it opens up a list of suggested tags (those that were submitted before).
But I want each blogger to get tag suggestions only upon the tags he/she entered? Is that possible in Drupal?
Cheers,
Amitai

I'm using the "From a list of categories and/or taxonomy terms, display (x) most recent nodes in full, followed by (y) nodes as teasers" PHP snippet to display some flexinodes. Right now it's showing them using my node-flexinode-1.tpl.php template. Is there a way for this page only to use a different tpl.php template?

I seem to have an odd issue: 1. user posts new forum item. 2. Item appears in "recent posts" and on the front page, but never appears in the index for the forum.

For example:

Post: http://www.chesmontastro.org/?q=node/1286

Should be in forum: http://www.chesmontastro.org/?q=forum/11

I'm following the Internationalization module documentation:
http://drupal.org/node/67830

A post with this content (the 'e n d o f f i l e' string is not literal so what follows can be read here):
#!/bin/bash
/usr/sbin/sendmail -t -oi minus-minus e n d o f f i l e
From: user@server
To: joe@server
Subject: [test here]

`cat hola.txt`
e n d o f f i l e

and Input format 'Filtered HTML' displays in the front end as:

#!/bin/bash
/usr/sbin/sendmail -t -oi

How can I prevent the 'EOF' from being interpreted?
Thank you.
