Wondering why I haven't received my certs yet. I k

Wondering why I haven't received my certs yet. I know many got theirs weeks ago. I also remember them saying there may be a delay on the rest of us getting ours. I have been on vacation so not sure what the situation is. I notice no one talks about them anymore. should I be concerned. they told me they have my address. Hate to bother them again, I know they are busy.
