Hi John - there isn't really any official public forum that JWs use to talk to each other - JWs are generally discouraged by their leadership from forming or joining such groups. That's not to say that there are are a few that exist - https://jwtalk.net/ for example , but these tend to be heavily "policed" to stop ex JWs getting involved , so you might have trouble signing up.
You might want to do some general research before getting too involved ( JWs do kind of "love bomb" the ( very ) few people who show an interest - especially people who are lonely and don't have many friends ). Look at www.jwfacts.com for example.
For your information , JW is basically an American MLM style religious publishing / property development business. It is not dissimilar to the Mormons - a group of generally nice , sincere people who are very busy doing a lot of religious and other organisational activity thinking that this is "God's work" and controlled by a USA based group of men who are regarded as God's sole representatives on earth. Many view it as a cult - it certainly has a lot of the characteristics. Be careful.
