Spreadsheets have always been a very convenient mode of information gathering, surveys etc. There are several ways to create spreadsheets and share them with others.

Num Sum is another way of creating the spreadsheets online and sharing them with others. It also allows you to peek into the spreadsheets created by other users, if you feel like you can import the spreadsheet in your account to modify or use it as per your requirements.

To start using Num Sum, you need to undergo a small sign-up process, once your account is created, you can start creating, sharing, saving, and importing the spreadsheets (either from other users or from your computer).

Once you choose to create a new spreadsheet, you will come across a page which has a full featured spreadsheet creation enabled, as shown below.

Once created and saved, you can get to see the other options like commenting, rating sharing etc.

Invitations can be sent either by entering the email addresses or by inserting the Num Sum username, rights to edit the spreadsheets can be decided by you based upon the Public or Private option as shown below.

I liked Num Sum; this for sure is a nice way of creating and sharing the spreadsheets.
