Genealogy Mailing lists can put you in touch with other people who are researching your ancestors.  Sometimes you find long lost cousins who can help you discover new family information.  Sometimes you can learn about the community that your ancestor lived in--which could explain that unusual occupation!  Cyndi's list has this information about Mailing Lists http://www.cyndislist.com/mailing.htm  

Rootsweb has two helpful sites http://surhelp.rootsweb.com/srchall.html

and http://lists.rootsweb.com/?cj=1&o_xid=0001029688&o_lid=0001029688&o_xt=9872  

An old standby is http://genforum.genealogy.com/

Give mailing lists a try--sometimes the ones that come right into your email can provide you with new insights into family research!
