Hi all!!  I am new to Inkscape and really love it so far even though I have no clue of what to do.  The post I was reading says you have to post to forum to comment, so here I am.  LOL.  I started using Inkscape to do a puzzle and I wanted to say thank you for the puzzle capability.  

Welcome :) Feel free to ask about any things you get stuck on here.

If you click on the Help Menu > Tutorial in Inkscape, there is a set of tutorial from basic to more advanced on there.

I would also recommend 'logos by Nick' on youtube, very good stuff once you learn the basics.

Indeed, welcome!  I'm Roy Torley and I contribute to the Inkscape community by writing a tutorial.  By writing a tutorial, I am able to learn Inkscape solidly, and I can turn around and share with everybody else.  I invite you to try it.  The table of contents is at:

If it helps you on your journey to visualizing what you imagine, then we're all having a great day!

Best wishes for the summer,

Roy
