[wp-forums] login for forums does not accept my email

[Joan Weise]

I would ask this in forums except forums does not recognize my email number
and jetpack says my username or password  is invaled. I am confused about
everyones username being admin, how does the system tell them apart. Maybe
my senior brain is just dense.
anyway here is info. blog is MostlyShinyThings, email joanjweise at gmail.com.
Thank you for any help.
