Hello, and welcome. I've standardised the markup on your page about mouse cursor and acceleration, so that it is ready for translation. The basis of our markup is explained in Typographical Guidelines.
There was a problem, though, on the Tutorials page. Please don't manually add translate tags (<--T:9--> for instance). It breaks the translation system. When an administrator marks additions as ready for translation the extension will add the necessary tags to the new sections.
Please take a few moments to read through the relevant links from Tasks and Tools where you'll find helpful tips. I hope you have more helpful hints like this Please ask if you are not sure of the appropriate place to add anything.
