Hello @tonys. Nice you could join us. If I was you, I'd go to 'youtube' and enter something like 'computer for beginners' or something like that in the search bar. 

On here, when your 'NEW' shows that you've got mail, click the 'NEW' box, and you will see who has replied. Click on their name and it will take you to their post. 

To reply, click 'Reply', type '@' and a menu will drop down. Click on the name of the person, and when you 'Post', it will go to that person.

I'm sure you'll figure it out. 

Take learning about your computer slowly. You won't learn it all at once.

Take care.
