Challenges for my Multicursor workshop

challenge1.txt

// a) 'Nstructive' should be 'nStructive', please fix it
// b) And give me a comma-separated list of all companies mentioned in this email

Nstructive leverages agile frameworks to provide a robust synopsis for high level overviews. Iterative approaches to 
corporate strategy foster collaborative thinking to further the overall value proposition. Organically grow the holistic 
world view of disruptive innovation via workplace diversity and empowerment through a partnership with Talentota.

Nstructive brings to the table win-win survival strategies to ensure proactive domination. At the end of the day, going 
forward, a new normal that has evolved from generation X is on the runway heading towards a streamlined cloud solution 
provided by Yuhuman. User generated content in real-time will have multiple touchpoints for Talentota.

Capitalize on low hanging fruit to identify a ballpark value added activity to Lecterna's portfolio. Override the digital 
divide with additional clickthroughs from Yuhuman. Nstructive's immersion along the information highway will close the 
loop on focusing solely on the bottom line.
