Should i upgrade to iWeb 09

From this forum you can learn that iWeb is not available anymore. And the iLife 11 package disappeared as well.

So you have to search around on eBay.

And iWeb was never insecure.

This link will take you to the only updates (no upgrades) that are or will be available for iWeb 3: Apple - Support - Downloads. As Wyodor told you iWeb is nada, no more, kaput, etc. Apple has decided to go another way, up to the iCloud, and have dropped both iWeb and iDVD.

Both of those apps still work so if you want to get a copy of them while there are still relatively easy to find I suggest you do it soon. A good place to start is Amazon.com: iLife 09.

OT

Here are the requriements for iLife 09. The limiting factor of having an intel chip affects iMovie and parts of Garageband. The rest looks good to go with 10.5.8.

Yes. Perform a custom install and select just iWeb. Move the current iWeb out of the Applications folder beforehand. Once you install iWeb run the updaters from here that apply: Apple - Support - iWeb 3 Updaters
