I have problem posting comments where log-in is required. My(one of a few) user id is 'solarmd', with associated [email redacted]. But your system won't let me log-in as [email redacted], when it insists I must log-in as scyang@wattminder. I'm kind of stuck in a no-man's land?!!!
The blog I need help with is solarmd.wordpress.com.
