The best way to help is to focus on an aspect of the site that interests you, to look for webpages on the net that I have not included, and email me the URLs.
If there is some topic or country about which you are especially knowledgeable, then obviously it is worth focussing on that.
The major search engines offer the best way to start, but I often find that quite obscure webpages have links sections that lead to other useful pages, so it is worth looking at lists of links on these pages. In other words, it is worth exploring the potential of the web's hypertext capabilities.
I must emphasise that I only want to include webpages that either provide political information/data or are the WWW presence for politically active organisations. Websites that are primarily commercial will not be included.
You can best get the idea of what is suitable by looking at the existing links on whatever pages interest you.
