Display confirmation message after successful sign-up

Description: After a user successfully signs up, a confirmation message should appear on the screen. The message should say, "Thank you for signing up! We are excited to have you on board." The message will be displayed in a visually noticeable box for a few seconds before disappearing. This will confirm to the user that their sign-up process was successful.

Describe alternatives you've considered

Redirect to a Welcome Page: Instead of showing a confirmation message, the user could be redirected to a separate welcome or dashboard page after signing up. This would give them a clear indication that the process is complete but would involve an additional page load.

Email Confirmation: Sending a confirmation email immediately after sign-up to notify users about the success of their registration. This is a common alternative but adds a layer of dependency on email services.

Modal Popup: Displaying a modal dialog box with a success message, requiring the user to click an "OK" button to close the popup. This gives explicit confirmation but may be seen as intrusive.

Additional context This feature helps improve user experience by giving clear feedback on the completion of an important action.
