The site owner, jcgriff2, has many friends who are active in other communities. Many joined Sysnative due to their respect of his contributions in helping others. That respect is a two-way street and has been returned by appropriate recognition. Others are involved in BSOD Analysis at other forums and joined here only for access to information about the specialized app.
As you are apparently well aware, Sysnative is a relatively new forum, with the major focus on continuing development of jcgriff2's BSOD app. If we are able to provide help to people along the way, all the better.
Regarding members you know from other sites, it is expected that they will continue helping at what you refer to as "home"
BTW, anyone who is under the impression that the object of this forum is to "recruit" members from other forums is completely wrong. It is very sad that you felt it necessary to register here anonymously. One can only gather that was out of fear of retribution at another forum, although I certainly hope that is not the case.
