Module development and code questions

I downloaded the mailhandler-5.x-1.1.tar and am trying to work with it. I have couple of queries:

1) In the fromheader if I don't want the default "From Header" to be the author but the "To Header", what do I enter here?? do I enter Sender, FromSender, TO:, toheader. I tried couple of things and it did not work and I tried a search on this forum/docs, but could not find anything.

Hi,

I just tried to add a new toolbar set to my FCKEditor so I can choose the Buttons I want to have and can still use DrupalFull and DrupalBasic. So I added this code in fckeditor.config.js:

I'm building a module that has a form, which, when submitted, will take the fields, run a database query, and display the results. I built the form, and set up the validation method. When I got to the submit method, I had no idea what to do. I tried to return a table, but it would give me a 404? I've literally searched for hours and I am at my whit's end.

Did I completely miss something in the docs or am I approaching this completely wrong?

Thanks for the help

The subject pretty much describes what I'd like to do. Any tips?

I want a node labeled something like "My account", which displays the sign in/sign up form if you're not already signed in.

If you are signed in, I want to run custom PHP code which will have access to the authenticated username/email address.

I'm looking at 2 different approaches (I'm a total newb) but not sure if either are right...

I've written a script that I'd like to have running on my site. I'm guessing to do this I would have to add it as a module and then enable it. Here is the code I tried using to get this to happen, which i modified from the j_query_interface module,

nta.module:

I've never seen anyone do this, but it seems reasonable to me: Is there a reason why variable defaults are not set in the install (or update) functions?
