OK I installed Joomla for the first time today!

Every folder that needs to be Writeable was marked Unwriteable at the install process.
I got the same webhost and exactly the same CHMOD settings on my mambo site.
I have to raise my CHMOD to atleast 775 to be able to write to them at the Joomla site, If I use that, would that be like "taking candy from a baby" for hackers?
Maybe something to do with SafeMode?... I don't know what value I got on that but it's the same on both my webhost's and the mambo site is working perfectly with that.

Please help! 

Just search for 'permissions' on the site, there is a score of topics on this. Normally, directories should be 755, and files 644. Only change them when you need to install a modules/component or change configuration.php, and change them back to the original value after that.
