Hello All.

I have a some question(s) regarding Field Level Accessibility:

1. My goal is to add a field to an object (eg. Account should hold a udf "NumberOfInteractions"). I want that the field should only be available to certain applications within Salesforce (eg a custom application - ResumeApp). I have attempted to do as mentioned above but the field is always visibl/accessable from other appliations as well. I want to hide the field in applications where its not needed. It will be used in both the force.com and the Apex/VisualForce pages I am building. 

2. How do I share my profile with other members of my team, where by in my absense another member can have read/write access to the data in my profile without having to log into my profile.

Your help will be greatly appeciated. Thanks

Sumit
