I can access my account on ELU on my Android smartphone just fine (Droid RAZR running Android version 2.3.5), but if I try to enter chat from ELU I get told I need to log in. So I click the login link and give my credentials and it tells me I'm creating a new account.
Note: I've seen this behavior off and on lately in webkit browsers. Sometimes I have to get in via Firefox. After a while it usually begins to work correctly again, but on my phone so far no luck.
