S’mae Martyn,
Just so that you know, we generally post here in English (or provide an English translation) so that learners of all levels can understand. There is a thread here for posting in Welsh though - Be' 'dach chi'n gwneud rwan? A phethau arall yn Gymraeg - A topic to practice Welsh, open to all!
If you want to chat vocally, have you joined the Welsh Speaking Practice group on Slack? You can have video and/or audio chats with individuals or groups of all abilities there. If you haven’t, just send an email to admin@saysomethingin.comfor an invite.
