Using the Renewal Link in Membership Renewal emails allows you to have a direct link for the patron to renew their membership. This link creates a renewal page for each patron that receives the email and populates the Member Form with their member name(s) and their current membership level's button highlighted. 

The membership renewal link will show the levels that are currently available for online sales, unless the constituent is a member to another level. If the level the constituent is a member to is not available for online sale, Altru will allow them to renew at that Membership Level regardless of the status of the Membership Level's Web Form. This is because the patron is already a part of that Membership Level and the Membership Renewal Link prepopulates the web form with the user's current membership information. If the Membership Level is made inactive the patron will not be able to renew at that level when accessing the Membership Renewal Link.
