The key to networking is that you should be able to find people with similar interests - and that they should be able to find you.
I was looking at all those who were researching Irish ancestors today, and was struck at how many did not include the word 'Irish' in their profiles. Yes, of course I also searched under 'Ireland', but we must make it easy for others to find us. Places of birth or death, dates, names of spouses, maiden names - all these can help someone with like interests find you.
I have just had a look at my Profile, and found it to be lacking in information! So I am about to improve it. Perhaps yours needs improving too?
