I was trying to put some input into one of the tutorials... but when I click Edit Tutorial, all the original tutorial text becomes removed....

Please fix...

Unless every tutorial is acting this way, it helps them if you're more specific or give links.

Tutorials have always been broken and were supposed to be completely replaced by the wiki over time. I'd suggest you go ahead and use the wiki instead,

i think they're all broken :\ ...

I haven't checked out the wiki yet tho.
