Module development and code questions

Maybe I've missed a step on this one but here goes.

I have a Drupal installation that ultimately contains a Flash application. That Flash application needs to interface, to a small degree, with Drupal. So, instead of reinventing the wheel, I thought I'd piggyback off of Flash Remoting and XMLRPC. (This may be my fundamental flaw here.)

Is there a mailer that has any of the following functionality?:

- The ability to send email to all users based on user group.
- The ability to pre-populate the email with the referral URL (for example, if someone click on the Mail Function from page 1 of a book, it should be able to populate the email with the location of page 1 of the book)

If not, I would be willing to pay for a working module that can do these simple tasks.

I'm getting double slashes "//" in url. For example..... http://www.example.com//?q=node/1

At near the end of the url, there is a double slashes.

I have been customizing the code all last night and today encountered this. The problem is I cant remember exactly what I changed. i have been changing alot of codes, and removing some codes.

I checked function l() and function url() but those code was untouched

how to hide locked menu item in the navigation menu ??

I was trying to create a custom module... I was looking at how other modules where developed and copying ideas.

I came across this PHP statement and I couldn't understand what it really was trying to do...

can someone please help me out... what does this mean?

switch($op ? $op : $action){
case '1':
do this
break;

case '2':
do this
break;
default:
do this
}

What does the "$op ? $op : $action" do?...

Thanks in advance

Hi,

I've just moved from 4.4.2 to 4.6.3. Previously (possibly because I had the BBCode module running) line breaks in my text were auto-converted to BR tags. However, under 4.6.3 the BBCode block doesn't do this so I am using the 'Line Break Converter' in the Input Formats.

My problem is that it uses P tags not BR. This means that when you view the front page there is an automatic line break between the text showing who posted the article, when and the taxonomy terms, and the main body.
