I was on line and could not sign in. Then later I was able to.
I did not think too much about it as the internet is funny and does funny things. Plus, it is always possible that the site was being worked on. I can understand doing it during the day as that is when everyone else works.
I do enjoy the site and did not consider a small time as being bothersome. Now, if it was for days, I would be having withdrawal systems.
