I always wonder about these “write a post in [number] lines.” I’m pretty sure it means “sentences,” because it would be hard to figure out how many characters fit on a line based on the font and the width of the line (for me, it’s 600 pixels). So we’ll stay with sentences.
I’ve been working a lot with GIMP (the GNU Image Manipulation Program) recently. It’s a poor man’s Photoshop, and you can also use it to create word art and image quotes. It does more than I need it to do, and the price is right (free). The people whose YouTube channels I’m visiting to learn it also work with Inkscape, apparently better for creating logos, and Blender, with which you can create animations. I think I have my hands full with GIMP, though; maybe I’ll play with the others a little bit as I get better. Really, I think GIMP is all I need.
I see by my line counter that this is line 10, meaning the next one will be the last. Hope all is well at your end.
