To receive XMR you only need to provide the payer with an @address where they can send funds to. Most of the time it's easier to just share a QR code and let the payer scan it, instead of copy-pasting the alphanumeric string. With the GUI every generated address come with its QR code. Make the person scan the QR code with the Monero @wallet on their phone and receive your XMR in minutes. Remember you can generate as many addresses (subaddresses) as you want. This is useful if you want to keep funds separated for any reason.

The members of the Outreach Workgroup heavily use Telegram for coordination and matrix/freenode in minor part. If you want to help, you can contact the workgroup on one of these channels. It is quite structured, so you'll probably be directed to a coordinator.
Monero is not only committed to making a fungible currency, but also to continued research into the realm of financial privacy as it involves cryptocurrencies. Below you'll find the work of our very own Monero Research Lab, with more papers to come.
