For two decades, I got my 40k fix at one of two discussion sites. First there was Portent, which started in the 1990s and was for a time the premier news and discussion site for all things Games Workshop. Sometime in the Aughts, the proprietor had enough, and sold the site to some of the administrators. That became Warseer. There was a seamless transition - new accounts were needed but everyone kept their handles and so things went. I eventually lost interest in being "current" in 40k, but continued to chat with 2nd edition enthusiasts.
I also developed Conqueror: Fields of Victory on Warseer, and the site hosted a "sticky" threat where one could actually read how it came about and discussion about what mechanics it should use.
Alas, a few years ago there was an attack on the site that knocked it down for months and when it came back, most of its users had gone away. Since then, a few straggled back, but it was mostly a ghost town, a vast site populated with conversations that were frozen in time.
Further complicating efforts to revive it, the site owners refused to authorize a much-needed reorganization, nor were they punctual about updating site credentials, which meant users had to click through warnings to even get there.
It's been down for a bout a week now, and while it has not year reached the "site not found" stage, I fear the end is not far off.
It's a reminder that the internet is by its nature a very temporary thing, and a beloved site with thousands of users can vanish in the blink of an eye. Warseer may yet come back, but I think it will only continue its zombie existence.
A large part of the problem is the competition by facebook (the site has a page) but I have no interest in giving my content to tech billionaires. I guess I should check to see if any of the other contemporaries are still out there.
