Help me find - Lost internet drawing site

Hi.

It's been a few years since I was drawing intensely. I used this site and I used Proko but I also used one site that I can't remember the name of. I felt it was a good complement to the other drawing I was doing here and on Proko because this site (the one I have now forgotten) was focusing more towards drills, such as filling a paper with straight and precise lines that went from one point to another. Or drawing oval shapes that was tilted one way or the other and doing this over and over again. It really helped me to get more precise. I would like to pick up where I started but I can't remember the name of the site, I can't find it in any of my history and when I try to search for it using google I can't find it either because I don't know what to search for. Perhaps someone here will recognize these drills and know the name of the site. Thank you.

Is it maybe Drawabox?

Hi Tizioh123!

Yes I believe it was Drawabox. Thank you!
Drawabox is a little bit weird way of learning and I wouldn't recommend it as the main source for anyone. But if you are drawing a lot it might be worth checking out a little bit. At least I got something out of it. What do you think about Drawabox?

Hi Thestripper,
I noticed in your thread that you spoke a little of your experience doing Drawabox. I am considering doing Drawabox to help me improve on my line work and perspective drawing generally. On LOA I am currently working on developing my understanding of the human anatomy and have been doing the 30 minute classroom sessions. I've watched a number of YouTube videos of artists' experiences; any thoughts or your experiences doing Drawabox would be appreciated.
