Maggie,
I would suggest you move to
phpAuction (also free in
Fantastico), as it has more fo the features you mention whereas Noah's does not (at least the free version --- and I hope you have seen
this thread with regard to Noah's).
Don't let the "php
Auction" name scare you! This foundation can function in many more manners than just a simple Classifieds or Auction format, but there are more advantages if you "move up" to this script.
I am assuming that you are only somewhat "experienced" with everything that goes into web-tech, so keeping things simple and easily managable by taking advantage of the "one click auto-install" aspect of
Fantastico seems very appropriate for you, and thus with the added features and other distinctions that would serve you well, phpAuction is worth looking into.
You can see many of the features live on the demo sites offered at the Official phpAuction Website (where you can also find all kinds of Support should you need it), since they also sell it to the general public outside of Fantastico.
