After some advice and thoughts on this one.
Have a well established community on a .co.uk domain name, something like vintagebike.co.uk.
The community is mainly uk focussed but equally has members worldwide. Always felt the .co.uk helped the uk members but put non-UK members off over the years. Tried for .com at various times but missed out at auction well over ten years ago and the price from the current owner only goes up.
With the new gtld release purchased vintage.bike however many years ago it was. Only setup as a redirect currently, however currenlty considering moving the domain lock and stock to this domain name.
Should I leave well alone or will the gtld benefit long term. Not done much with the site for too long, plan a big refresh of which this could be a core part.
