Re: Sex MUGEN 2.0
If you're referring to the Spanish website, yeah, it's pretty much dead. Used to be hugely popular, with quite a few uploads, characters, sprites, everything. It was a true H-mugen forum, with people collaborating. Then less and less people posted new stuff and the updates dried up. It was still good for a monthly checkup, but it wasn't exactly a mecca of H-gaming anymore. The mods/site owner decided to do something stupid and close the site down; when it was re-established, the site was restricted to members only. Pretty dumb since it was in Spanish and not everyone spoke it, so that would whittle down visitors and views even more. And after a bunch of revisions to the site in which all the great content was removed, it's now a ghost town. I think there's a SINGLE post there (or two) from Jessica Smoke, to upload her character. Pity.
If you're referring to another website, well, I've never seen any other forum in which H-mugen is discussed currently, unless it's a Japanese one (I'm sure there are more other than the Hinanjo website, which is still fairly active).
