CakePHP 2.x App Needing some additional plugins

I have a CakePHP App/Project that needs some additional functionality worked in :) It uses multiple databases to pull/save data to, this is because it is basically a Web frontend for a game built also using the same databases. 1.) I am needing reCaptcha CakePHP Plugin integrated into the project for the Login page as well as the Register page. 2.) I am needing Gravatar integrated (there are several helpers out there) into the project as well to match the current logged in users email and display it next to where the username of the currently logged in is. ([login to view URL]) 3.) I need the current Signup page when submitted successfully (the signup function in [login to view URL]) to not only create an account on the master database account table, but it also needs to create the account on the admin database account table. (There is already an example of this with the ban/unban functions as they affect both databases at once) 4.) Fix CakePHP Error Handling (Right now it just shows generic CakePHP errors not found when [login to view URL] is set to debug 0 (production) ) I want it to show a generic Error page (Like 404 Not Found, We couldnt figure out your request) This CakePHP project uses multiple databases that are prebuilt to integrate with another project. If you have any questions please contact me!
