This weekend I found (by accident!) a Welsh learners meeting arranged by “Menter Iaith Sir Ddinbych” called Bore Coffi held in Llandyrnog.
They have all sorts of speaking and cultural events going on - details are on their facebook page (Search as above) or website: www.misirddinbych.cymru/ - I have to say they were most helpful and I really enjoyed my time with the people who were there!
Hope it helps someone else!
