The domain may be difficult for your users to access or remember. The dashes and the .me could easily be forgotten or mistyped, as well as "tutorial" vs "tutorials".

When trying to generate a domain I like the "say it out loud" test so I can see how potential users may try to explain it to someone if they're recommending the service in person. Lots of "dashes" is a red flag .

Just a suggestion, I see that myfreetutorials.com and even freetutorialsfor.me is available. May want to check those out.
