You say "notify us of site problems" in this section's description, so I will: you have malicious trolling and stalking going on here, and you don't do anything about it. One of your most popular, helpful and respected members has now left the forum and explained why, on her profile. It looks like either you have no judgment at all or you simply aren't moderating your forum. The behaviour of the loathsome individual referred to is a continual disgrace about which countless members have commented adversely. You had many opportunities to do something about it before it did such damage to your forum. I'm not surprised you have ongoing member retention problems.
