Hello, Larry! I'm so glad you took a moment to introduce yourself, and so very delighted to see you're from the U.K. and interested in joining in U.K.-related WikiTree discussions, which I've seen there is a great deal of interest in here!
There is a United Kingdom project at WikiTree that is a 'top level' project encompassing sub-projects for England, Scotland, Ireland and Wales as well as some Crown dependencies, if you're interested--and this top-level project serves as a central directory for all that is happening in its various sub-levels. You can find this U.K. Project at WikiTree here:
WikiTree Project: United Kingdom
And I like your suggestion that it might be nice some day to have sub-groups for specific conversations like G2G for various project areas. To make sure this suggestion is seen by the right folks at WikiTree, I suggest you edit your question here to include a tag at the bottom for "improvements" "g2g" and "tools" just to make sure you're covering all the bases, and all our best technical wizards at WikiTree will see your query and give it some thought.
