Module development and code questions

I am new to drupal but I have 4.65 installed. I am looking to integrate my first module and started off with TAC 4.7 but I seem to be having trouble with the installation. I placed the module in the module directory. I activated the module and I have given myself access but the page I get when I click on settings>>taxonomy_access is messed up.

"The module is currently disabled, but must also be disabled in the modules admin page in order for it to be properly disabled.
To properly enable this module, select 'enable' here and save the configuration.

I am having trouble figuring out what MassMailer adds to PHPList. Is it only an interface or is there some functionality there?

On a side note, this is typical of the problem I have reading Drupal documents. Components are labeled as doing WXYZ, but YZ is really done by another component, and it's never really clear who does X without reading the full documentation.

i realise 4.7 is still beta

but, there's several modules for 4.7 that require the image module (and talk about it)
but there's no image module for 4.7 - and the 4.6 one just doesn't work.

so - what's the deal? I'm confused.

Hello,

I've just finished writing a filter that transforms an article from XML into HTML. (If you are curious about WHY: it's the internal article format used in Free Software Magazine).

Now: I am _extremely_ concerned about server performance. I simply cannot afford to do one transformation every single time an article is displayed, because it would kill our server (which gets dugg/slashdotted frequently).

Hi,

I'm planning to try any Drupal image galleries module but i'm not sure which one is working module. This is for my personal images posting and having different galleries on my family website. I've tried with image module so far and i could not able to create perfect gallery using this alone. Hence i'm looking experienced views on existing Drupal modules. I've tried Gallery 2 also and i'm not able to configure or install it cuz i'm getting this error whenever i try to launch it.

I want to develop a module.
Any suggestions on what kind?
I am a begginer.
