Modifying the WordPress Plugin

General information for the website: It's a charity website called Do Forward Num. of web pages/modules: 1 Description of every page/module: Website: Basically this is a website where people post/upload images of items and then other people apply for the items. From the received applications, you choose a person you want to donate the item. Once you donate the item to the person (it means deliver the item), you get point for your donation and the point is added to your profile on website (point here is called Karma Point) Logic is: You get Karma Point when you do some good things. New Development: I need a calendar based plugin on my website (somewhat like Android's Calendar App), with dates being displayed, on clicking date a text area below opens. Here you can write. Now here I want to allow people to write their any good activities they did in their daily life and for each activities they get certain points and is automatically added to their profile. Example: I opened calendar. Clicked on 2nd Feb Date, space for text opens, I entered details as below - I gave 100 USD to a homeless guy at station today. - Today I donated my unused cycle to my landlady's son. - Today I made a charity of 200 USD at ABC hospital. So I entered 3 good things, so I shall get 3*(certain points) as Karma Point and is added to my profile. Note: Karma Point is already working. Database and everything is all set. All I need is this new functionality to be added as a part of earning Karma Point. Description of requirements/features: Note: Karma Point is already working. Database and everything is all set.
