Although I'm not sure it will help or make any difference, I've reported a pm to GNHQ which I received from someone, who may or may not be the person with dual membership. I ignored it at the time as it was very childish and spiteful, and it never occurred to me to report it!
I'm still not sure whether most of the PMs being discussed are those sent recently by a single member who no longer posts, or whether nasty PMs are rife!
I think it may be too late. i would be surprised if there are anymore in the forseeable future after today's threads. I do hope so. At least if it is all open on the forums we can see who having a go at is saying what.
Can I urge anyone who has received an unpleasant or unkind PM from another member to tell GNHQ? There are now a number of threads that suggest some members have sent private messages which have upset the recipients. Don't walk out on everyone, please! Report it!
