The URL to the site itself is
https://fadingobsessions.com . By adding the my. before fading obsessions.com takes you directly to the forum
As you say, that site, just like Project Shapeshift, has a limited number of posts per day. The latter has an age limit, fading obsessions has not, but the majority of the members at both sites are older than the average at other sites. If you joined in 2001 and 2004, respectively, you have seen most of the topics discussed many times, so you may not post as frequently.
Also - My Fading Obsessions was launched in 2004, but the forum made a new start in the beginning of this year. So it is one of the oldest sites, but at the same time a new site, still growing. Some join the mentioned sites for nostalgic reasons, others because they like that kind of pages - a little more old school. They might not be huge, at least for the moment, but friendly, open minded and interesting. Personally I am a member of them, plus this site and MyPancakeAddiction and I am trying to get back in at EDC (for some reason I can't get in at the moment). I think all the sites has something unique
