"Very open to helpful suggestions"
Site has no comments section. So...yeah.
Visited with a handful of browsers and found no issues (though admittedly, can't log in, not a member), but the system kicks back no errors visiting with an up-to-date Chrome or Firefox.
Worst case, just get an extension that lets you change your browser ID string. Unless it's using some of the proprietary OS hooks (which I can't imagine) it'll never come up.
Mountains of molehills and all that.
