What are Tags ?
See Full Tag Cloud
Tags are keywords or one word descriptions that help to identify a NXT project on NXTLOG. When NXTLOG users create a project they can enter a tag or series of tags to descibe the category of their project, or a specific feature of their project. This makes searching for types of NXT projects easier.
For example, entering a search by a "vehicle" tag may bring up any style of NXT robot that moves on wheels, while a tag like "bluetooth" may bring up any NXT robot that incoporates Bluetooth communication.
Since tags are inputted by users, not all robots that fit under a certain category may come up in a search. The best way to get to know tags is to experiment searching with them. Try typing some tags in the search box or clicking on tags on a project and see what comes up!
The tag cloud on the front page of NXTlog 2.0 shows which tags are used more than others. The ones that have bigger sizes are more popular than ones with smaller sizes.
