ASP.net Web Application Help

Question

Hello all,
I am new to this forum and I would like some help from my respected seniors.
I am trying to develop a ASP.Net Web Application using C# or VB. First of all prefer me whether C# would be easy or VB for the following scenario:

Below are the requirements:

1. For All Users:

• Text-chat feature will allow users to chat with the available online users.

2. For Registered User:
• Allow users to create new folders and sub-folders, to store (upload) files.
• Allow users to perform move/copy/delete operations on folders and files.
• The percentage of storage capacity remaining and used should be displayed on the top.
• Automatic versioning system will record the version/revision information when a file is replaced/overwritten
• Team management feature will allow users to work in teams (by inviting other existing
registered users). The activities of the team include access to the password protected area for
the team, uploading files, commenting on the uploaded files (discussion), polls, automatic and
manual reminders to the team members.

3. For Administrator:

• Approve/Reject new team requests; update/delete existing teams.
• View all the files and folders uploaded on the server.
• Allow to perform delete operation on any existing file/folder existing on the server.
• Delete account for any registered user.
• Define and Edit storage capacity and other limits such as Maximum file size allowed for
uploading.

Queries:

1) As, every user will have his/her own PERSONAL profile page then how will the system redirect the user to his/her PERSONAL profile page after hitting Login?
2) How this chatting feature can be developed?
3) How this storage capacity would be assigned overall?
4) How Administrator will manage all this?

I am totally confused.
I have developed SRS as well. but in coding I am totally stuck as I am not so good in coding. I thought Visual Studio 2010 would help me effectively in this case, and I am trying but couldn't find any way for this to be done.

Please help me out.

I look forward for your replies.
