"Manage tasks and activities for your projects" i am going to try this template for my own purpose. But i don't have any idea about how they did in sharepoint. we can do it in asp.net, but i don't want to waste time. It might be easy in sharepoint.
So, how can i proceed with this ? Someone guide me i'm new to sharepoint
