Module development and code questions

I have two modules (A and B). A is a node extension module and B is a more of an administration/backend module -- but completely seperate of A.

I want to include a form to edit an A node in module B under a tab. Essentially what I am doing is giving people using module B specific permission to edit individual A nodes (not using drupal perms). I can't use aliasing and I can't have the people use module A directly (API only).

So instead of having the url be:
q=node/{A-id}/edit

I'd need the form to show up as
q=B/edit

I'm developing a small module and want to ensure in perm hook that the user must be registered.
How can i achieve this? If it can't be ensured in perm hook, then tell me where.

Thanks

Hi,

I've been getting to grips with Drupal (started with 4.5, now 4.6), and have solved, most of my problems, though I'm having to teach myself PhP and MySQL as I go.

But images have me stumped.

I've done the 755 thing with the directory, I've confirmed that images are there (because a correct URL calls them, and I can access them in my web admin area).

But when I look at the HTML code in Browser View Source it seems to me that the module is creating duff links.

I can't get node_privacy_byrole to do its job in 4.6. I have tried everything. Even creating new nodes and new users, but it seems to impose no restrictions at all.

I am also using organic groups module but I thought they were supposed to compliment each other.

I'm excited about the new "Event" module, which seems to me to be on the way to resolving that critical issue of GMT versus local time.

Regarding weblink. Can we expect it to be released for 4.6? I'm ready to pay for this feature.

I'd like to have a block to post links, just like at http://newstoday.com public broadcast column (3rd from left).
Just a title for the links, url and short desciption. Commenting would be great. Would that be possible to do in Drupal?

Let me know how can I help and how to donate.

Thank you!
