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
I have "played" with Linux off and on for a while. The last one was for 1 year when 10 broke everything. The only thing that has held me back from a 100% ditch of M$ is those couple games I like to play and I have become the goto guy in my railyard for broken windows computers. Oh I hate 10...
There is Wine on Linux that will run most Windows programs, maybe try to install and see if those great games run under it? It even comes with Windows note pad, for what it is worth...
