Module development and code questions

To those who were able to test Robert's enewsletter module, do you think it can already be used in a live site? Am planning to use it as soon as I'm confident it's stable enough for live use. Any feedback would be greatly appreciated. Would really want to use a newsletter at my site to increase traffic -- always had my eye on the enewsletter module since it has the batch send feature (my host limits the sending of mails to 200 per hour)which I need. Thanks in advance! :)

Hi Ppl.. I have known Drupal for only about few months and am very much impressed with it. I am wanting to migrate one of my sites to Drupal(I've already made couple of Drupal based sites).

For doing this i need to have a custom module developed. I have looked around but could not find it anything similar to it.

Hi,
I searched (probably with the wrong words ;) ) but didn't find an answer to my question:
http://drupaldocs.org/api/head/function/arg says "Avoid use of this function where possible, as resulting code is hard to read. Instead, attempt to use named arguments in menu callback functions.See the explanation in menu.inc for how to construct callbacks that take arguments."
Where can I find the explanation or an example?

Thanks

Ralf

I've searched and read the docs, but I'm not seeing an answer. As far as I can tell, the pager doesn't hold onto the sort order of the table. Sorting works fine, paging works fine, but after choosing a sort order you can click on a pager like (next, etc) and the sorting is gone. Is there something I need to do to keep the sort order around? Looking at the pager code, it looks like it just doesn't bother with it. Should I hack the pager code or is there a better way?

When I create content, for example a story, where does is text from the "Abstract" input field used? I don't find it anywhere.
Thanks for your help.

I followed the instructions for installing the massmailer module, including changing the permissions of phplist/bin/phplist to 0755 but cannot send mail and am getting the following error:

You do not have the php command line executable in your system path
and it cannot be located in /usr/bin or /usr/local/bin.
Please edit the modules/massmailer/engines/phplist/bin/phplist file to correct this.

Any help would be great.

Thanks!
