Hopefully someone that really knows something about this will be along to explain, but in the meantime I suspect it's related to
this.
Other general searches on 'vBulletin + reputation' give further but sometimes possibly spurious detail (version differences perhaps, or maybe is a very new feature that's different from before - or I'm a bit useless at searching!).
What I thought may have been spurious I've decided probably isn't. Have a look here, doesn't necessarily mean it's what is/will be implemented here but time will tell I guess. Hopefully there's a way to utilise this practically for reading purposes as per Slashdot or SoylentNews that use slash code? In any event well done admins!
Yet another edit - I should have thought to look
here!
Out of interest I saw that link included 'vb3' as part of the URL, which led me to go looking at available vBulletin versions. From what I see the latest version is 6 .. not being especially familiar with vBulletin, and without being able to find the detail anywhere, it's not clear what version PPRuNe uses?
FP.
