It appears that the Heroclix database site MyHeroClix.com has shut down. Given the uncertain status of Heroclix this isn't a surprise.
It's too bad, because it was rather useful for tracking your collection and warbands.
Another useful Heroclix related site, WhoClix, is also gone, apparently a casualty of the sudden shutdown of AOL on Oct. 31 of last year.
The WizKids site is still up, although apparently inactive. There are no new posts.
It might be wise for HeroClix fans to get what they need from the site before it disappears.
