Module development and code questions

I'm looking at multi-step forms with Drupal. I've had this working on Drupal 5, and am migrating my module to Drupal 6. I've noticed that core forms.inc now uses cache_set/cache_get for storing form information between requests, where it used to use $_SESSION. I also have need to store form information between requests, and actually need to get my data stored before the first form request (so I need to do it outside $form_state['storage']).

I have successfully installed ed_classifieds on several sites successfully, however, on a particular site I installed it and before I had a chance to enter in any catagories someone placed an ad. I could not get it to work properly after that.

hi,

I want to develop a custom content which should be included of 3 pages or 3 stories.
Those 3 pages should be accessible as one content. Also on click of create that "X" custom content ... user should get an
option of creating three pages in tab.... (he/she can create one page at time) but the thing is it should be viewable as tab...

Can someone suggest whats the way to go??
Should CCK and View be used or can Book be tailored for this kinda thing???

Many thanks in advance for your views...

I created profile fields (e.g. Country, Town, University, Interests, etc) and then I created 3 dummie users and entered the same Country, same Interests, same Town and same University. All the fields turn into links, which is cool, because when you click on "London" yo expect to see a list of all users who are in London... BUT.....

Whenever I click on any of user's town that says "London" it displays only 1 user and that is the Admin.

Hi guys i want to customize the appearance of the shippable product i was loocking for a template to modify but i cudnt find it any one knows how to do that?

I seem to be unable to add a dynamic menu item to a different menu than the main Navigation menu.

It needs to be dynamic so the link text can change, but it also has to be in its own menu so it can be in a separate block.

Should I give up on using the menu system and bypass it by making a PHP-evaluated block? Or is there some way to place a MENU_DYNAMIC_ITEM into a different menu?
