Also, I feel configuration settings fall too short: I'd like to be able to change the font and color of my text or hide offline contacts, just to mention two missing options. I had some problems when trying to organize my contacts into groups, with groups completely disappearing from my screen (but easily recovered by restarting the program).

Of course, no software app is perfect and neither Spark is. What's more, the program includes some other useful tools like a basic note editor and a task list. Spark also has some extra details that are hardly found in LAN clients, such as avatar support, conference rooms, voice chat, spellcheck and even a special tool to capture anything on your screen and send it directly to any contact. I especially like the emoticons sets included in the program, as well as the usage of a color code to distinguish between different statuses (online, away, busy and so on). Spark displays a nicely designed interface that makes it really pleasant to use. It uses the Jabber protocol which can be configured to use either private or public networks, depending on the plug-ins you install on your server. Of course, there's the possibility to use one of the big IM programs like Live or Yahoo! Messenger, but Spark is faster and far more secure. Spark is an IM client that you can use in organizations such as schools or companies to allow people communicate with each other in a quick, efficient way. Different email signatures and personalised calendar invites are two other features available within this standard package.

Queries such as a name, a subject or even the first letter of a word will pull up the most relevant results. This application utilises what is known as a natural language search.
