Hey watch out! There's a hacker on the loose hacking the groups, you need to protect your groups!
Hey, buddy. Haven't heard much from you in a while but I hope you are doing okay where you are.
I don't mean to push, but are you okay? It's been 2 years since you last responded to a comment and it's kind of concerning. I'm sure you moved on from these works or are just busy, but a little message confirming that you are still here would be great.
