Dad has been complaining about the same typekey login problem that Kev has. Here’s what I think’s going wrong, based on my use of his computer & account.
When you want to comment
1) Click sign in
2) After it takes you to the typekey page, hit login. (If it doesn’t keep your name/password, re-enter those then hit login).
3) You’ll be returned to the website, but it won’t look like you can comment. Don’t hit sign in again! Instead, hit refresh.
4) You should get the comment box. Happy commenting!
