Why did she want to add me on Skype randomly?

[Brogan]

I met a girl nearly a year ago at a convention and we added each other on Facebook. We've only messaged each other twice, both at the end of 2013 and start of 2014, and that's it.
She randomly messaged me today asking if I had Skype. I said no since I forgotten my password and replied "Damn, was gonna add you". I told her may have written my password down and she said to "recover it". I did that and she added me.
She kept leaving emoticons like 😜 and :/ (that one was when I said I forgot my password).
Anyways, I told her I'd get back to her when she added me because I wasn't in the house, so she said "Okaysss 😜".
We don't really talk, do I'm wondering why she randomly asked me for my Skype name. Any suggestions?

She probably wants to impress people with the number of friends she has on Skype. Or maybe just to make herself feel good.

It's hard to guess.
Maybe she wants more friends on Skype?
Maybe she taught it'll be good to add you. Since you both know each.
Since she hardly sends messages to you, we can't guarantee that she likes you.

It doesn't means anything special if a person adds you but never messages you nor talks to you.
So if she is talking a lot on Skype, then there may be a chance she likes you depending on how the conversation between you is.
