The client-server distributed ObjectGrid instances combines the resources of multiple JVMs on multiple servers.

Managing the registered users of your website can be a time consuming process, particularly if you have a large number of them, all of whom have various roles. Each role or user profile has access to certain information or tasks (if they're administrative) within the scope of your website. You have the tools to determine the extent of their access by using the backend interface modules. To explain, we'll use the Party People website to show you how to stay on top of managing your users and their profiles.
In this article by Tracey Porst on User Management, we will look at the User Manager to deal with the scenarios that can, and inevitably will, arise in your role as content editor and web master. These include:
- Managing existing frontend and administrative users
- Establishing and editing new user accounts
- Managing username and password issues
- Dealing with problematic users
- Tying in user profiles with site contacts
- Communicating with users
One trap that many web site owners fall into is spending lots of time pulling in traffic but not offering anything to encourage visitors to return. This leads to a rather self-defeating cycle where the site owner is forced to constantly promote their site to keep bringing in the same number of visitors, eating up valuable time that could be spent improving the site in other ways.
Fortunately, a little time invested during the early days of building a site can pay off very well in terms of encouraging repeat visitors. In this article by Lesley Harrison, we will:
- Learn what is meant by making a site "sticky"
- Look at ways to build conversations with visitors through comments and contact forms
- Make our visitors feel like they are part of a community with gravatars, polls, and welcome messages
- Find out how to encourage visitors to subscribe to the site, and keep them coming back
