Post installation

Hello - I need to nuke the contents of all of my 'revisions' cells in my DB for my nodes. There's a significant issues with them filling up and causing pages not to render properly. I'm very cautious when it comes to executing sweeping SQL statements because I'm not as experienced with MySQL syntax. So, I wanted to run this by all of you:

         UPDATE `node` SET `revisions` = '' WHERE `nid` >= 1 AND `revisions` != '';

Obviously I want to back up my table first. I believe this should select all nodes with a current revision entry, then delete all contents of the 'revisions1' cell.

TIA for any pointers or confirmation I've got this right before I go and nuke all 913 rows revisions entries! :-)

I have installed drupal 4.4 and most functions appear to be functioning normally.
For example, I can add content to the home page and it will show up, create new users successfully etc.

However when a user - even the admin - tries to edit their settings under 'Edit Account' and clicks on the 'save user information' button - the 'Edit Account' page just redisplays.

There is no grey info box at the top of the screen telling you the changes have been accepted and also no error displays. The page just seems to redirect to itself.

Hello all.
Here is my second issue.
I'm putting my website (http://ecdllibre.sourceforge.net/drupal-4.4.0/ - only in italian, sorry) up and running and I'm starting experimenting with Drupal.
I love it.
My problem is about comments to forum topics: everyone count as double in the forum "replies" panel. That is, after the first reply, the forum list shows 2 replies to the topic. If I add another reply, then 4 are shown.

Does anybody uses the Neighbor module with the latest drupal?
I'd like to do that but I get some error. Well: the module has no name into dhe module list, and I can use it in any way after activating it.
Sob. Sigh.
:)

Is it possible to remove the authoring information from a node? (name, date, etc.)

If it makes a difference, I'm using the chameleon theme.

Configuration lets me set how many words before homepage story trailer cuts off to 'Read more'.
Rather than doing that, I'd like to be able to compose a short trailer first paragraph and then
insert markup that stops the trailer there, no half sentences, with the rest on the new page.
Is there an option in Drupal for that?
