Module development and code questions

I am in the process of trying to integrate the identity_hash module's functionality into a few other modules (I have already created a email-based login module based on it), but this time I would like to allow anonymous access to a node when there is a valid identity_hash in the url args, but even when the "access content" access control is checked.

A bunch of us are starting development of a new genealogical module, possibly to be called simply family. We're just settling on a name at the moment (and sorting out initial schema design etc.) and would love any feedback on people's opinions about the name.

First of all, I know these [blah blah forums] and drupal integration thread has been posted [a number]*10^10000000000 times, but I've searched high and low and can't find a modification to integrate the Drupal and Invision user database together, anyone got any ideas to such mod?

Hi.

I have inherited a site built with version 4.4.2 of Drupal. I have found a new module (Simple Access) that I would like to install. I am not sure of the historical architecture of modules on Drupal. Has the “format” for modules changed since version 4.4.2 ?

Unfortunately I cannot find old 4.4.2 install files or I would simply build a test site and install the Simple Access module. The other obvious choice would be to upgrade Drupal. But there has been a ton of customization on this site.

Any thoughts.

Thanks

I installed the excerpt.module semi-succesfully because when I try step 3 in the 'INSTALL.txt' file, I do not get to see the 'default workflow'. Can anybody help me with this?
