That forum has its ups and downs. On the one side, you have the chance to post blogs and look at other people's tastes in music, religion, and the like. There is a forum that has numerous topics to post about. They are cracking down on pedophiles (which is more than can be said about the Craptower Society) and spammers.
The down side is the trolls on the forums. The Health/Nutrition forum has about a dozen trolls that methodically tear apart any posts about vitamins, herbs, additives in foods, and whatever food is good for you. They have their own set of medical journals (sounds anything like the Watchtower Society?) that, if it's not there, you have no right posting about it. This might be good if they just bashed promoters of MLMs that are questionable, but many posts I have had ruined were generic products (alpha lipoic acid) without brand names or distributor names, or about MSG and aspartame (two additives that are poisons that will ruin your brain). This renders that forum useless.
The Religion forum frequently has JW threads. You are free to post anything about the religion (or any religion) there, including devil worship and atheism (and there are numerous threads about Satanism). The JW threads are dominated by active Witlesses posting what the Watchtower Society programs them to, and the apostates that analyze them rationally and cite other Web sites liberally.
Notice that the forum is open to anyone 14 years and up (those under 14 risk getting banned until you turn 14, or seeing mature content that is inappropriate). There is swearing allowed (however, excessive swearing and adult topics are not permitted). And you do have to guard your identity, but they are aggressively cracking down on that. So, those cautions aside, if you so see fit, sign up and enjoy! And it's free.
