Cool saves me hunting for a link everytime. Thanks!

Normally, it should not be necessary to rebuild bitfields manually ...

I've installed three modifications that have given me a link at the end of the install script telling me to run admincp/index.php?do=buildbitfields.

Yes, in older Versions this was necessary - now it should not.

When you turn on the debug mode, the link is available under vBulletin Options... Don't see any use to this hack.

so its available when you're not in debug mode?

and kirby there's been plenty of instances, even with your hacks, where people have had to rebuild the bitfields manually inorder for it to work correctly.. even when they install the hack right.

Yes it is available if you use the direct link when not in debug mode.

What else does debug open up?

Add/Edit Options
Admin Help Manager
Queries executed and explain
Templates loaded

just the first things that come into mind now.
