Sometimes certain communities (hobbyists/like-minded folks) are so small that people know each other well, for long periods of time. Conflicts and personality clashes are inevitable. (I belong to another forum where this is true.)
New members of the forum do not know the history or conflict issues that may already be present.
On the other hand, there are myriads of personalities out there who like to stir the pot.
So far on this forum, I have found 99.9% of the posts to be thoughtful, educational, respectful &/or fun loving. All are great to have on a forum.
Thanks to those of you who set this place up and keep it friendly.I'm so glad after so many years that I got up the courage to join.
