Ok well there is a couple things.
- What kind of wish list and where are these "items" they're adding going to be coming from?
If your wish list is something like a "product feature request wishlist" then that's different than a "shopping wishlist".
A Product wishlist would just be a matter of inserting the persons name, topic, description of the wishlist into a database and having a page list all of them verbosely.
As far as the shopping one is concerned, I don't know enough to help you out... maybe someone else could.
- Are you going to use a "database" or a "textfile".
I assume Database because you posted in the database section. But a file would work too. if removing/changing records isn't important.
