Wasn't sure if this is the right place to mention this, but the LFS101x Introduction to Linux course on edX is currently unavailable. Given it's a pre-requisite for most LFS201 students, might need fixing
Thank you for bringing this to our attention. We have reached out to edX to rectify this - we hope enrollment will be re-opened soon for the new session that will start February 20th.
Looks like it's fixed, thank you!
