Why are they hiding....

Remember that whatever email address you are using for Facebook, people can search for you that way. You can just copy and paste any email address in search on Facebook and any account that is attached will show up.

I don't think so....I guess depending on YOUR settings.

I was with girlfriend last week (she created a business account) and tried to add me via using the email address in the search and came up empty! I changed my settings, then she found me and once I accepted I changed my setting right back to the way they were

There is a setting under Privacy that asks - Who can look you up using the email address or phone number you provided? and you can choose a) everyone b)friends of friends c) friends
I have freinds selected on mine
