So, you want to send a motherfucking XMLHttpRequest (XHR, or commonly and falsly known as AJAX.) Too bad, just ran out of motherfucking XMLHttpRequests; but I still have one regular. XHR is not magic. It does not autofuckinmagically send things the way you want them do be sent. It does not do the thinking for you. It just sends an Http Request.

You get a hold on such a prime beast like this:

Conclusions to the JS meeting held Feb 21st 2015

1. Room stars in the meeting room
2. Do not unstar previous messages upon starting a new meeting
3. Room Challenges
4. No more organized room challenges, instead a list of resources that are refreshed weekly hosted at https://github.com/JavaScriptRoom/
5. Job postings within the room
6. If it's a regular they can pin it. If it's just some programmer can pin/star for a few hours and that's it. If it gets spammy, too out of hand we can readdress.
7. Room owners promotions/demotions
8. Jhawins - keep as is
