The Web offers various ways of communicating with experts and others who have an interest in your topic. You might join an online mailing list, for example, to send and receive e-mail messages relevant to your topic. Or you may wish to search a newsgroup’s postings. Newsgroups resemble bulletin boards on which messages are posted and connected through “threads” as others respond. In addition, you might log on to real-time discussion forums.
To find mailing lists, newsgroups, and forums, try one of these sites:

Google Groups http://groups.google.com
Tile.Net http://tile.net/lists
NOTE:Be aware that many of the people you contact in discussion forums will not be experts on your topic. Although you are more likely to find serious and worthwhile commentary in moderated mailing lists and scholarly discussion forums than in more freewheeling newsgroups, it is difficult to guarantee the credibility of anyone you meet online.
