Ran,

This topic has been discussed extensively in the 393 newsgroup. Autoprop, maxprop, Kiwi prop and Gori. There are 92 messages dealing with this subject. You might find your answer there. Below is an example:

Ran,

At the home page, click on "messages" at the left. When this page come up there's a search function at the top. Type in Autoprop and a bunch of messages will appear. If you have problems leave a message at the site. Due to a lot of spam new members have to be approved to post. If you leave a message I'll approve you and you'll have the same access as all members.
