I mean that it is rather common practice for internet projects that
every member of community has one one login that works for all services
this community uses. This is called "single sign-on" or SSO
http://en.wikipedia.org/wiki/Single_sign-on

So far I have only one login that works in bugtracker and I thought that
I can used it for other python.org services as well. My mistake, sorry.
In my previous post I've just asked about how many logins should I have
to use sites that share common design and navigation element you may see
on the left? What are other services except bugtracker that require
registration? I know there is at least wiki should allow login to edit
restricted pages.

My mistake is not a reason to close this bug report. OpenID just should
wait for SSO system to appear, if of course there will be something else
besides this bugtracker to login. Like code review system.
