I'm not getting some pings. I'm getting pings from ping groups, but not anything else. I've gone back to threads to check if the person's replied to me, and they have, with a ping; except I've had no event telling me I was pinged. :/

If they try and edit their post and reuse a ping, it won't work. Do you think this could be the case?

It may be. I didn't realise that, thanks. I'll keep an eye on it and do some double-checking etc. I got your ping just fine. :)

Awesome! Yeah just let people know that they have to actually type out the @ name here again and not reuse the same one. I will close this up. Let me know if you are having problems again.
