Hi, I joined this forum recently and am looking for parts 3 and 4 of the DIY TENS guide. I haven't received a response from the admin and don't see any recent activity on the forum. Do you know if this forum is still active? I saw that you liked one of my posts and figured at least someone was active here. Please let me know if you have parts 3 and 4 or know how to get them. Thanks so much!
