Major update.

As for iframe, I asked the Creator to do something about it after one overly clever user loaded all sorts of nonsense through them. The Creator simply decided to remove them.

Regarding the Spoiler, I also asked to add it a long time ago, but it never got around to it.

Otherwise, I'd like to bring back ranks and the old-school reputation system, where you could put +/- under a post.

And in general

From a technical standpoint, the forum is extremely outdated, not to mention that its functionality has only decreased over time (first it was ranks, then they introduced limited search, inability to upload files for unregistered users, etc.). If HeroesWorld needs anything, it's a full-scale modernization and a more powerful server, but that requires funding and an active administration.

The forum requires a global modernization... but who would take it on...

P.S. Personally, I am against huge signatures; many people simply abuse this. It's too annoying to scroll past them...
