For adding the content from the front page itself

Monday 11 April 2005 6:39:51 am

Problem 1:I have two groups, (1) Identifier and (2) Non-identifier
For Person who is identifier has just log in by entering his/her name and ID and for Non-identifier person has to fill the form for subsciption.

Problem 2: Also I want to keep the facility in website that if the Identifier user want to change the content of the website he/she can change without entering in the backoffice i.e. in the admin area.
Means There is one "Personal Space" in the website (i.e. in the front page) for the Identifier user, from where he/she can easily change the content and add the content too. Is it possible?

Please anyone can suggest me how I can make it possile and how I can solve these two problems.
If there is a link which gives the guide line then its very helpful to solve my problems.
Thanking you
