Not sure whether this should be tech support or general discussion, but I wanted to report that I just attempted to create an account here using two different versions of Chrome on Linux (both their current Stable and Unstable), and each of my 5-6 attempts failed with a near-instant “We were unable to detect whether your account was created…” message.
I don’t have any unusual cookie blocking enabled and I’m a member of probably a dozen other Discourse forum sites, never had an issue like this before. (I ended up switching to my Android phone, which is how I’m here now. So, ultimately I got in — problem solved, from my perspective. But I thought I should probably let someone know.)
Also, mostly unrelated but in the same vein, your TOS page currently contains a bunch of language like this…
The Website is owned and operated by company_full_name (“company_short_name”).
Which I’m guessing probably invalidates it, from a legal perspective. (But, IANAL.) 
Just FYI.
