Deprecated - Drupal core

I would like to have all new users enter their email address as their username when they register at my website.

Is there an easy way to enforce that without hacking up user.module?

I'm not a big fan of the way node previewing currently works. The preview is spit out above the form. I'd like to split the preview out onto a seperate page (request) so I can show the previewed node only (not the form) and two buttons below it titled "Go Back" and "Submit".

Anyone have a better way of doing this *without* serializing $form and passing it around?

Thanks!

I thought a suggestion to the general audience like this is more appropriate than to the specific care takers of the comment/node modules.

There are efforts to generalize taxonomy and content (such as the category module). I think one thing to do that is helpful to these efforts is to fuse the comment and node modules. Conceptually, it makes sense to say that comment-able ought to be a property of a node. When allowed, a specific type of nodes can be commented on. It should help modules like the forum module too, in setting specific permission to special forums.

No javascript files like drupal.js, collapse.js, autocomplete.js in drupal-4.6.6.tar.gz.

Is there any particular reason chx ?

I looked in to cvs.drupal.org misc directory it contains all those js files. Well can i just add those to the misc directory.

I'm working on tweaking my server because I'm having a problem with running out of memory. I've read a bunch of the docs about optimizing the mysql database here, but there seems to be contradicting information regarding persistent connections.

I have them turned off right now and am considering turning them on, but I'd like some feedback. Does it actually help with memory?

Could use some insight on this issue.

Why doesn't Drupal put meta tags specifying the generator, i.e. <meta name="generator" content="Drupal x.x.x" /> ?

I believe somebody takes this into account. Even WordPress do it.

Or is it not important?
