Hello- My club website is ideally set up for what the club needs at the to moment ( using webplus X6 ) Ie it does not need rebuilding or re-developing . However I have been told that it will be to be rebuilt if I want to attain the following goal.

Updating it is a bit of a pain. Several people forward the different changed file to me and I do the update on different pages - These updates are in the form of updated spreadsheets - photos , power point slides and word documents. Is there a way or bit of web software that allows different people to update different parts of the website from different locations?
Ideally a few select people would have access to different pages of the web site (say via a password ?) This would enable update to go through quicker and without my involvement

Any help greatly appreciated.
