Why are you attacking my husband’s grammar? He didn’t do anything to you and he didn’t do anything but write the way people speak. Please stop!
Ignore the above. My husband assures me you guys are just being playful.
Not if you don’t force the possessive.
"Is there any problem with Mrs. Rhymer?
“Is there any problem with Mrs. Rhymer using the Dope?”
"Is there any problem with me?
“Is there any problem with Mrs. Rhymer and/or me using the Dope?”
Avoid the possessive and it sounds better, IMHO. The minute you use “my using…” you have to match the other name, too.
Welcome to the jungle, the beast is yet to come.
Glad to have you, we’ve heard many good things about you.
We nitpick here: That’s what we do. The fact that we’re nitpicking small, insignificant things about Skald is an indicator that we don’t have any big things to nitpick about him. This is a good thing.
That’s many folks’ first mistake.
Just playing. 
Nitpick: you can’t really nitpick big things.
Thank you, Chronos. If you go to the location we previously discussed, you will find your cats, mostly unharmed.
Well, they seem like big things to us nit-pickers 
(But I long ago stopped correcting people’s grammar, unless:
- They explicitly ask for advice, or
- Someone else starts the nitpicking, as in this case.)
To enlarge a bit on what Musicat wrote, it also depends whether you construe “using” as a gerund or part of a participial phrase. Those two choices have different shades of meaning, and the writer must decide which one he/she wishes to use.
Welcome aboard, Kim!
