Maybe this plugin goes in the direction you are looking for: http://community.elgg.org/plugins/797106/2.1.1/digest. But it sends notifications / email to all users and not admins only. Also, I don't know what exactly is included in the notifications. But the plugin might be a starting point to customize it regarding your requirements. At least a daily summary would surely be better than a separate notification about every single activity which would flood your inbox. But isn't the site activity page also a way to keep up with the site activity without getting emails abut every single action?

Please notice that if you are using memcached, then you will need to reset that.

Profile Manager has this option, you need to change the "Profile_manager" settings and allow users to change their username or just allow the admin to change it.

Thanks! I will download Profile Manger

Not in the default system log.

I haven't found the default system log useful for *anything*.  I routinely disable it on all projects as it just adds overhead.  I would suggest you create a custom log of only what you need.

Since i am new to developing for Elgg, i am a little lost on how to create my own system log. Has anyone already perhaps developed a configurable plugin for logs.

I don't think there is a plugin that offers a configurable system log.

Take a look at the file engine/lib/system_log.php. The functions in it handle the creation of the system log entries. What you would need to do within your own plugin:

• Unregister the default system log events. This is the easiest part (http://community.elgg.org/plugins/1441338/1.8.0/elgg-1819-no-logging),
• Register your own system log events. Basically, the events will get fired in the same way as the Elgg core events but they don't execute the Elgg core system log functions but you would need to provide your own instead.
• Include modified versions of the functions defined in engine/lib/system_log.php in your plugin. You would have to modify the functions according to your requirements, i.e. what needs to be included in the log entries. These functions then get executed when your log events get triggered.
• You might also need to modify the logbrowser and logrotate plugins to work with your modified system log functionality.
