Couple of fun updates for this Friday I've been working on. 

1st - - Send Postcards on Avalanche and Base. Built using @AIWayfinder 

Chainmailer supports AVAX and Base and creates Postcards that are stored entirely on chain without IPFS (using native SVG). You can send messages to people as an NFT rather than simple blockchain messages and they will have permanence and can be read on opensea, in your wallet (if SVG supported), or on Opensea. @MagicEden doesn't seem to support the syntax I'm using, however but YMMV. 

2nd - Launching - a @AIWayfinder community focused site to highlight my own Wayfinder Research projects and Youtube Channel. Will be expanding the webpage to have a 'Community Highlights' for projects put together using Wayfinder for anyone who wants to participate.
