Honestly, I haven't had much contact with any of the ones you listed. I'll have to get a look around their sites and see what kicks up.

There are a *lot* of groups and sites out there that, and this is a bit of a rant that might tick a few people off who read it later, are in it more for the excuse to scare themselves witless than to actually try to get any research done. They have not (or choose not to have) taken the time to learn protocol, safety, or even how their own equipment works, or know a false positive from a potential anomaly. Plus a great many of them are trespassing on private property without the proper permission that frankly, is not only necessary for legal purposes, but to keep their own credibility. They in turn make the entire field look bad.

Also, beware of *any* site dealing with the paranormal that's trying to sell you something. There's one that's a glaring example of this, and I'm not going to mention it on a public board. You'll know 'em when you see 'em.

In the end, keep a healthy skeptic's mindset when looking at any group's site and their information. That goes for mine too. My group tends to play and joke around, this is very true, but when we buckle down we're all business. A very good indication of whether or not they're "serious" is to read through their information/explanation pages, and also to see if they have loads and loads of pictures, especially those of "orbs". 99.9% of all orbs are contamination of some form, usually dust, pollen, moisture, rain, or something else airborne. Nothing really paranormal about them at all. It's that .01% that interest me. LOL

Of course I don't mind! And truthfully? Both. Let me explain.

In more than nine times out of ten, any kind of "paranormal" activity is completely benign. Most anomalies are in the form of scent, sound, some visual, and "feelings", plus blips on various and sundry monitors and meters. Less common are voices, EVP (voices recorded on tape/digital media), and the occasional "touch", where someone might feel something on their hair, their hand, shoulders, etc. It's very, *very* true that you have, in just about any given situation, that one has more to fear from the living and the hazards on the site than any of the ghosts.

But there are spirits that I've run into, and others have as well, that are agressive. They are *rare*. Let me repeat that. They are RARE. I don't like using the label "evil" for several reasons, most of it being that it's a judgmental morality call on something with very little information. I don't use the word "demon" either not because I'm not a Christian, but rather because using a religious term for an entity gives it a lot more baggage than it necessarily warrants. We don't *know* what ghosts are. We don't *know* what any of this is, for sure. That's why we're out here, really.

To be perfectly blunt, the nasty ones are out there. The chances of finding them are very, very slim. Those that make a huge deal out of them are usually shooting for the drama factor. Hope that helps...I can clarify a bit more if you need me to.
