I'm not Tatjana, but perhaps I can help, too.

"Beth Cambridge" may be a name from the old forum - at least, I can't find her here.
For reference, you can search for someone by using the magnifying glass icon in the top red bar of the forum, then typing in someone's username.
The search will show forum threads at the top and users at the bottom -- for example, if I type in "kate" then I see "KateF, Kate23, kateblair, kategarrett, katewakefield" and a link to show more which would eventually find you @katerobertson.
But searching for "Beth Cambridge" only brings up this thread, and when I search for "beth" I don't see anything that immediately jumps out at me.
