All the groups except for the Watercooler, which is open to all SIG members, must have someone 'authorize' the request.
Since we have moved to this new site, I have found myself unable to change your status from 'moderated' to 'valid' -- and I have typed your name in repeatedly.
I asked @lesliedow to help me with it, and she said she had already put a request into their tech support about that issue.
I am working on it. We are working on it.
I am so sorry that you are unable to participate.
We will resolve the issue. We WANT YOU to be able to participate.
Feel free to PM me if you continue to have issues. I don't have to accidentally find messages like this in order to answer you. I can answer you directly.
