I know there is a very sizable Irish Gaelic community on here (Gaeilge), but it would be nice to see some more Scottish Gaelic and Welsh, too.
Personally, I've found learngaelic.net a very handy resource for learning Scots Gaelic, as well as the memrise app. If you're looking for someone to write to, they do have a place called mylanguageexchange.com, that works like a penpal system with people looking for native speakers.
Always looking for more Gaelic enthusiasts, though! The more the merrier!
Buaidh gun robh leat!
