Well.... in reality - you should not run your server with "Register Globals" turned on.
You can check this if you make your own phpinfo file - and run it from your web browser. You can also find phpinfo in many server control panels.
make a file called phpinfo3838.php (or some other random number - so others can not easily run it!), with this inside.
Upload it to your webspace. Run from web browser.
If register globals says OFF OFF - you are ok.
If register globals is on, you need to ask your sysadmin why - or if you are the sysadmin - ask yourself why.
Register Globals is known to cause security issues with many scripts - not just aedating/dolphin.
Having it on is not recommended or desired for (almost all) php code users.
