A clever member of this forum used a blog page with only one entry as a guestbook.
Remember that if you add code to a published page, every time you update/publish all the extra code will be deleted, be careful with this.
If you want to add extra code to a page created with iWeb you have to publish it first, then locate it in your iDisk (it should be under iDisk>Sites>Web>[name of the site]). Open the page using any editor (Taco HTML is my personal favorite) and then add the code where you want it.
Some users make a "mark" in iWeb (something like "add code here") so they can locate the right spot without problem.
As i said before, you have to be careful as the next time you publish/update your site, all the code may be lost.
Most guestbooks require a server that allow php or MySql scripts to be run on them (which .mac doesn't), so your options are:
- a web-based guestbook that you simply link to (but won't be nicely integrated in your site)
- find some free server space with php support and check out ardguest (a GB system) and customize that to integrate with your site (perhaps with a custom html page in an iFrame)
- Use a blank blog page with comments as suggested above
Don't worry if you're not familiar with all the terms I mentioned in the second option, I didn't have a clue but managed to integrate Ardguest on my bands website without too much difficulty...
