Module development and code questions

I have an application where I'd like to assign users to a role programatically, if the user meets some criteria. I am finding this difficult to do, since Drupal appears to be unsetting anything that I set in the users_roles table of the database.

Right now, I use hook_user to add a portion of the user registration/edit screen that deals with the application's user settings. I've put code into the 'validate', 'update' and 'insert' options, but I've tried:

Hi,
I am fairly new to the Drupal system (but I love it!) except for the handling of images. I noticed that there are a few posts about this topic and I thought that I would share a method that I am using that has worked reasonably well for me.
It requires image_filter to be installed, and uses a user block to generate thumbnails of uploaded images. The block allows you to scroll through a list of the thumbnails and select your image - the image filter tag is generated in the block above the list (you still have to copy and paste it into the relevant text field).

(1) Lets have a menu called "Navigation" with an Item, SubItem, SubSubItem and SubSubItem this way:
Math -> Summer Contest 2005 -> Exercises -> Exercise 1

(2) I don't want the menu to expand further "Summer Contest 2005", so "Summer Contest 2005" is a leaf. This is, because I have the links to the articels on level deeper in the articel itself.

But I don't want to miss the breadcrumb. Let's say I am on "Exercise 1":
I want the breadcrumb: Home -> Math -> Summer Contest 2005 -> Exercises

Furthermore I want to have "Math -> Summer Contest 2005" expanded in the Navigation menu.

(3) Now, my current solution:

Look for the values of "type" in the table "menu". "Summer Contest 2005" and "Exercises" will have:
118 = MENU_CUSTOM_ITEM | MENU_MODIFIED_BY_ADMIN
= MENU_VISIBLE_IN_TREE | MENU_VISIBLE_IN_BREADCRUMB | MENU_CREATED_BY_ADMIN | MENU_MODIFIABLE_BY_ADMIN | MENU_MODIFIED_BY_ADMIN

If I disable the Items, they would have:
112 = MENU_CREATED_BY_ADMIN | MENU_MODIFIABLE_BY_ADMIN | MENU_MODIFIED_BY_ADMIN

Now, what I want is:
116 = MENU_VISIBLE_IN_BREADCRUMB | MENU_CREATED_BY_ADMIN | MENU_MODIFIABLE_BY_ADMIN | MENU_MODIFIED_BY_ADMIN

Changing this in the database (and flushing the cache) will truely do want I wanted, but it's not achievable with the menu module.

(4) So what do you suggest? A feature that needs to be added to the menu module? Or something to do with a new module? Or maybe another solution?

Does any of the available HTML editors support the Opera browser?

My web host limits the amount of mail I can send in an hour (200). Is the Simplenews module equipped to deal with this limitation? I understand that cronjob handles all unsent mail in the "maximum send time" setting, but I'm not sure if this setting/feature addresses this limitation. (Incidentally, my site is set to run cron every hour.)

Thanks in advance! :)

Hi,

I have noticed since the begginning of this week, my bandwidth have been going crazy, it has took 4 gbs since the begginning of the week, which is really not normal, and my online users have been going up to 3500 to 4000 users. I click on Administer and it always gives me this error for a whole bunch of nodes.

taxonomy/term/445 not found. and when i click on details they give me this in the location field : /taxonomy/term/445?PHPSESSID=8c816fbb34e89ac29352a34d3c26dcb3

and this repeats for all kinds of different nodes.
