Hi there, I'm new here too.
FB is so draining and forget Twitter, perhaps one could just sort text messages randomly on an old style cell phone and have fun that way?
I hope this site resists the temptation to allow a lot of advertising (M Zuckerberg's $45 billion FB seems like it is doing well in the advertising area though).

As for pictures, there a literally dozens of sites that have free photos you can use ( I will find my list and send it to you), I find many on the Wiki Commons , especially in the public domain (read old) are often good too.

I wiped my MS and installed Linux about 5 years
ago now, and never looked back, so if you get stuck on Ubuntu maybe I can offer a little help. The way I look at it is - I need holes, I use my drill, I need to process words or numbers I need a computer, but soooo often I must fix the x#d$@a&m computer to do what I want to do, whereas the drill just works until it dies.

Good luck here
