The easiest way is to install the Edit-This-Page package.
Log in to the web site as an administrator.
Click on Admin > Install Software > Install from OpenACS Repository / Install new application
Follow the instructions within Edit This Page (the link will only work after Edit This Page is installed).
Go to /admin/permissions and grant Create to Registered Users
Suppose you install a new site and install Weblogger, and you want all visitors to see weblogger automatically.
On the front page, click the Admin button.
On the administration page, click Parameters link.
Change the parameter IndexRedirectUrl to be the URI of the desired application. For a default weblogger installation, this would be weblogger/. Note the trailing slash.
Every page within an OpenACS site is part of a subsite More information). The home page of the entire site is the front page is a special, default instance of a subsite, served from /var/lib/aolserver/service0/www. If an index page is not found there, the default index page for all subsites is used. To customize the code on the front page, copy the default index page from the Subsite package to the Main site and edit it:
cp /var/lib/aolserver/service0/packages/acs-subsite/www/index* /var/lib/aolserver/service0/www
Edit the new index.adp to change the text; you shouldn't need to edit index.tcl unless you are adding new functionality.
Almost all pages on an OpenACS site use ACS Templating, and so their appearance is driven by a layer of different files. Let's examine how this works:
A templated page uses an ADP/TCL pair. The first line in the ADP file is usually:
<master>
If it appears exactly like this, without any arguments, the template processer uses default-master for that subsite. For pages in /var/lib/aolserver/service0/www, this is /var/lib/aolserver/service0/www/default-master.adp and the associated .tcl file.
The default-master is itself a normal ADP page. It draws the subsite navigation elements and invokes site-master (/var/lib/aolserver/service0/www/site-master.adp and .tcl)
The site-master draws site-wide navigation elements and invokes blank-master (/var/lib/aolserver/service0/www/blank-master.adp and .tcl).
Blank-master does HTML housekeeping and provides a framework for special sitewide navigation "meta" elements such as Translator widgets and Admin widgets.
