I have sent invitations to new authors to the course blog. In some cases, the invitation process went smoothly, but there are also problems.
Some users have received the initial invitation, clicked the "accept invitation" (some several times), and in the blog's Users list their status is "awaiting". Now when I try to resend them the invitation, using the user name in the list, they haven't received the "Visit Blog" verification - and thus haven't got the rights to contribute to the help.
How do I get them accepted as authors?
The blog I need help with is lahdentiedottajakoulutus.wordpress.com.
