Lists subscribing multiple issues

OK I've been trying to subscribe to internal for a few days and I just succeeded but it was tough. So, first issue is the form at https://secure.php.net/mailing-lists.php I tried using it to subscribe but it didn't work. I inspected the requests and found out that it was submitting to https://php.net/mailing-lists.php which was redirecting to https://secure.php.net/mailing-lists.php. This was losing the POST request in the process. The reason why seems to be this line: <base href="https://php.net/mailing-lists.php"> Once I tried submitting with CURL on https://secure.php.net/mailing-lists.php directly it worked and I got the confirmation email. I replied to it and so far I didn't get a reply saying that I've been actually subscribed. In the meantime I tried the instructions on the page to subscribe directly to the list:

Either send a message to php-whatever-help@lists.php.net (as in, php-general-help@lists.php.net)

Sending a message to that address (or to php-internals-help@lists.php.net) got me a message asking me to reply to confirm I wanted to post to the mailing list. I didn't want to. I tried php-internals-subscribe@lists.php.net and never got any message either. After getting the confirmation message after fixing the php.net form I got an email from internals-help@lists.php.net, so it seems that the "php-" prefix is not actually used? I tried to send an email to internals-subscribe@lists.php.net and no luck either. (I also tried mailing webmaster@lists.php.net and got address not found, this is getting really confusing!)
