Rhonda, you don't need a mobile number for Facebook. The reason why they want it is to confirm you are who you are and not trying to create a fake profile. All you really need for a profile is an active email address. For the account I have, I didn't use my mobile number, but I did add it later because it makes it easy for my friends to get a hold of me.
Thanks, Shaggy. I have a valid email address. I think it's possible that because it's the same one I used for my previous account, which I canceled, they want me to confirm by texting them from my mobile phone. They didn't require that the first time I signed up with that email address.
Maybe if I try from another email address, one not already associated with a previous FB account, it'll let me sign up without texting them. But, that still leaves my attempted account there, which, apparently, people can see (if indeed they really are requesting to be my friend) but I can't get into to modify or cancel without sending a text. And now, after all of this, I've decided I don't want one at all. It just reminded me of how much I despise Facebook.
I'll probably just redirect all the Facebook notifications to my Junk Mail folder and forget about it.
It's too bad that most everyone I know insists upon using Facebook as their main form of communication. I often don't get replies when I send email, and then when I see the person and ask them about it, they say, "Oh, I never check my email anymore. Send it on Facebook." Or, someone I know loses a loved one or has a baby or whatever, people act like I'm an idiot for not knowing about it: "It was posted on Facebook!" Or, I want to offer my help on a certain project seeking volunteers, only to find out that you can only sign up via Facebook. It's annoying. It makes me want to drop out of society, because this is not the kind of society I want to exist in. I suppose I should just forget keeping up with family and friends and trying to make a difference in this world. It's hopeless, unless I want to sell my soul to Facebook. I swear, someday very soon, I am going to the top of a mountain somewhere all alone and never coming back down. [/frustration-fueled rant]
