The overvoltage clamp is not an ESD protection, it is a protection against an overly high input voltage during use, preventing the transistor from being turned on if too high a voltage is being applied.  

The clamp will change the transistor from being switched on to being switched off electronically in case it detects overvoltage. It does not remove the voltage, only prevent a current from flowing. Sufficient ESD will still destroy the transistor. 

The whole protection part can only be constructed for n-channel FETs, and not for p-channel FETs for technical reasons: 

The protection circuits have to be powered. We need protection only when conductive, because that is when heat is created inside the transistor. When conductive, the source-drain voltage probably is quite low. So the only way to draw power is from gate. 

Now a pfet has no voltage on gate when conductive, meaning an active protection cannot be powered. 

Also, in amplifiers, where pfets are often used, it is a bad idea to use individually protected transistors. The protection circuits are not very precise, meaning the individual transistors will not turn off at the same time. Turning off only one transistor of a symmetric setup can lead to very bad results. 

I can't find a PFET protected against ESD
I have a site that I am migrating to WordPress, and I have a need to add properties that each of the users can edit (e.g., Address, City, State, Business Name, etc), along with some properties that Administrators can edit (IsActive, CanEmail) that wouldn't be displayed to the user.  In addition, I need to be able to display the properties in a table (similar to how the plugin, "Members List", displays, but with the custom fields displaying as well.

Given these requirements, I had attempted to use a combination of "Cimy User Extra Fields" and "Members List", but the members list grid did not have an option to display the extra fields created by the other plugin.

How would you recommend I approach this?

EDIT: 

So I guess the crux of my question is, what is the preferred method to add properties to the User?
