...what support? They barely reply any queries people post in their google groups. If you go there you'll see most people will try to reach them either due to servers down (the main issue at hand) or login issues which never get fixed (the longest standing issue, better create a different new subdomain) from what I've seen. I've also tried repeatedly to reach them regarding changing the token access, but with no luck. It's a free service so I can't complain, but the only support you actually will get is from other users, and for some scenarios that's not quite enough.

EDIT: Oh wow right after posting this I just saw they actually replied regarding the SSO/tokens issue most people have (SSO failed due to the reddit snafu, you end up with just the token and no chance to do any further changes to your account again). This has been an ongoing issue for over two years, I just saw they finally replied (I think for the first time) a couple of weeks ago.
