I would like to have below functionality created on Visualforce Page, Please help with the solution.

I have very good position in Trailhead Community and want to change my Email Address to Personal Email Address, so i can access it throughout my life. Can anybody help me with this ?

Though, I Found one solution but dont know if it works or not, find it below.

Log into "https://developer.salesforce.com" with the credentials which you want to change, and Goto "Edit my settings" and change your email id.

Please let me know if anyone has every tried this and outcome.

I Have Multiple Apex Classes and i want to decide which Apex Class to Call on Run time Based on the Record Value.
I want to make a Generic approach for this, i already tried with Tightly coupled approch like comparing record value with something and calling Apex.
I can definitely accomplish this with the help of Factory Pattern Classes and Triggers. But Requirement is to have this in Declarative Approach.

Thanks
