I am working on a website for an artist organization. We have been maintaining our member database using Constant Contact. I imported our Current Member list to a member-gallery CMS collection from a Constant Contact export, and added  fields for a Profile Image and a Gallery. Each item represents a member's record. I then created two dynamic pages based on this collection: one showing a list of members with galleries, and the other a detail page for each member.    I would like to create a Member input form to allow members to load/update their data. I (think I) need to link the member collection to the registered Member Area table so I can limit their edits to their record in the member-gallery table. Can you provide some guideance in the process to make this linkage, or suggest a better way to do this? Thanks Bill
