If you want to see who is having a birthday today (somewhere),
click on this birthday image or enter today's day and month just to the left in the "Day" and "Month" fields.
Then, leaving ALL other fields empty, click on "Perform Search".
Another good basic search is based on your gender and cities/towns you've
lived in. Select your gender in the gender field to left and, using the
"Cities You've Lived In" field to left, enter the names of up to 6 towns/cities
where you have lived, separated by a semicolon (;). Then "Perform Search"
