del.icio.us is an online tool for 'social bookmarking,' or sharing useful or interesting links with other users online.  Users can tag sites they think are relevant to a topic such as e-agriculture, and organize and share the entire list of sites they have tagged with other users. 

del.icio.us can be a little confusing at first, but it is a useful tool for sharing websites and we encourage users to play with it and try creating their own accounts to learn.

Briefly, if you click a tag in the e-agriculture del.icio.us tag cloud, for example , 'Latin_America_Caribbean,' you will be taken to the del.icio.us social bookmarking website and in the left column you will see the list of sites with that tag attached.

The first column on the right shows 'Related Tags,' other tags which are also attached to the listed sites.  These are useful for selecting subsets of the examples with your chosen tag.  For example, if, after choosing 'Latin_America_Caribbean', you want to see only the sites tagged both 'Latin_America_Caribbean' and 'English,' click the 'plus' sign next to the tag 'English' in the first column and it will show these sites.  The numbers next to the tags correspond to the number of sites tagged both 'Latin_America_Caribbean' and 'English.'

The second column shows all the tags used by e_agriculture.  These are grouped by region, language, type of organization, named organization, type of resource, and topic.
