Glad to see you are active on G2G and starting to figure out how WT works. I know that you recently joined the Ireland Project and I'm happy to help you navigate the early learning stages of WT if you like.
As for being unable to 'unlock' the Flax Name Study, you'll have to be patient and wait until you've been here for 30 days. It's policy, to ensure that you have had a chance to learn the basics. I have 2 name studies myself. We've all had to do this.
Welcome to WikiTree.... and, as I said, I'm here to help with more than just the Ireland Project.
