Firstly, if folks want Gloucestershire included in the midlands im happy to do that.
Secondly, the tagging of mines too a mmr is sometimes overlooked, however, the biggest nightmare is tagging to a particular area of the mmr. There are hundreds/thousands that are not tagged, for example, Cwmorthin may be tagged to north Wales, but not to the Blaenau region. This is something that the regional editors are (hopefully) dealing with as an ongoing concern. The difficulty is trawling through each and every mine to check it!
