This was done to remove spamming on the issues page.
What this means. When you sign up for an account on our Redmine server, you receive an email to confirm. Once that happens, you have a login to
gnuradio.org but are not yet a member of a project; what's called, appropriately, a "non-member." To do many things on the website, you have to be a member of that particular project, which means manual intervention by one of the website admins. All that means is that you ping me to make you a member of GNU Radio, at which point you can now post and edit.
We wanted to have bug fixes and ticket tracking open to everyone, but someone had to go and ruin it for everyone. The process isn't a big deal, though, and you can always use guest:gnuradio.
