My b2evolution Version: Not Entered
Dunno what to call it, but it's not a plugin and it's not something that lives in your skin. I guess that makes it a hack? Ahhh for the good old days of hacking the core!
Before you go there: a visiglyph is a customized visual representation of a commenter's IP address. After a comment is submitted the visiglyph will be created and prepended to the comment. Kinda like automatic avatars in a way, only different.
So ... uh ... where's the preview button gone off to? Am I supposed to pick the version before I get to do the preview thing?
