I don't personally do any theming for phpnuke/vB as I'm not sure if you can use vB as a module for phpnuke that will use the same theming template system (of course I could be wrong). I too use vB for my main site but Joomla as the CMS and both share the same overall aesthetic but use completely different theming or template systems.

As for nukemods creating phpnuke/vB templates, I'm not aware of any future plans to do this given the vB Community already has an extremely vibrant template community surrounding it.

I don't know about this .I am a fresher to this site.

I can't see this happening as phpnuke and vBulletin use their own, unique template systems. AFAIK, there is no way to integrate the two into one template system and the same can be said for most CMS' out there when used with vBulletin.

There are a few CMS' that will use the same template system as vBulletin such as Subdreamer, vBAdvanced, etc.

The only thing I can suggest is to find either a phpnuke theme or a vBulletin theme you like and alter them to match each other as much as possible.

Vbulletin theme can be modified easily (via admin panel) to match phpnuke theme..

That's true but I think he was looking for one template that incorporated both phpnuke and vB (although I might have misread it).

Yes, vBulletin is very easy to skin and the skins here are very easy to port over.
