Where to ask?

I have a problem - I don't know WHERE to ask my question. I can't get the function imageRotate to work in PHP 4.3.1. According to the php.net function manual the function is only supported up to 4.3.0. When I call the function I get "Call to undefined function". However - it works fine for other people usning 4.3.2. and I haven't seen any posts anywhere on the net about people having trouble rotatating images in 4.3.1. I can't really report it as a bug (or can I?) since the manual doesn't say it's a supported function. I can't post a question on the function's page (it got rejected). I don't really want to sing up on any more mailing lists, but if that's the only way, I guess I have to. If it was up to me, I would update to 4.3.2, but I'm on a web hotel and they weren't too keen on updating. Here is their setup, btw: http://www3.fsdata.se/phpinfo.php. The web hotel told me to ask you guys. Please, let me know where I am supposed to post my question. Regards, Mike Wehner Stockholm, Sweden
