About the credits: Where do I need to add them and what? On every page or on the htl-pages in the ACP only?

Kurafire has left vBulletin.org.
If you want support goto his website: http://www.everythingvb.com

What does it mean "he has left vbulletin.org"?

He won't log in anymore?

He has quit us?

What's happened?

OMG! Now I see...

Any idea what the hell that's about?

Euhm, i WAS planning to install HTL, cause the idea sounded nice.

Then i browsed a bit through the full rls hacks (old forum style) and found that on the newest 2 pages (50 rls's) only 2 ! used HTL :(

Then i visit here and i see KuraFire no longer posts here....

That was a bad decision. Detaching himself from this forum doesn't give me good hopes for the future and support of this hack.
I see he directs in all his threads to this thread:
https://vborg.vbsupport.ru/showthread.php?t=61939
but i get a no permission error, so no idea what was in there

NOT installing.... too bad, really sounded like a good idea.

[high]* BarBeQue pressed install :D

(oh btw, BBQ = BarBeQue)

So this will only work for hacks that are formatted for it?

yes.

Edit, i shouldn't say yes, i mean you can import hacks into it, but you would need the permission of the original Author of the hack you would like to import. ;)

Works like a charm on vB Gold! Cheers for this!
