Hey! Welcome to the site.....
I'm sorry, I don't know anything about PENS either (but at least I read it right Els

).
Just wanted to say welcome..... feel free to post anything.... this is a great supportive group and we can all attest to that!
Take care....... I look forward to hearing from you often.
