What is a Guild? How can I be a part of it?

One of the best parts of our community is that it allows people to meet and make connections with others, regardless of where you live. guilds are smaller communities within Major League Hacking. Whether you come in with a guild or not, you won’t be hacking alone. 

Who organized Local Hack Day?

Think about the tasks you do on a daily basis. Is there anything in there you can automate? Social media posts? Sorting your inbox? Sending out the zoom invite for the family meeting?

Build a chrome extension

It’s time to upgrade your web-surfing experience. Build a chrome extension to help you out - it could block distractions, change the background color of a webpage, or do anything else you dream up. A Chrome extension to help you submit on devpost might even be a good move.

Write a script to check the weather

Checking the weather can be useful in all sorts of applications - from alarm clocks to reminders apps to websites and everything in between. Write a script that can return the weather to you
