How web to lead forms are used to assign leads to queues or users in Salesforce?

Hi,

When dealing with Web to Lead, when you are setting up your Web to Lead form, you can set the value of the field 'Lead Source' to a specific value. (In fact, you can have this field be a hidden field so no one evens sees it.)

Then, you can set up a Lead Assignment Rule which says if the Lead Source field is equal to 'Web', then have the Lead go to the Lead-Open Queue.

Hope this helps.
