1/ Most of the hacks here should be compatible with vb 2.3.0. It's normally just a mistake made when replacing or adding code that leads to people believing the hacks aren't compatible.
2/ There is a quick reply hack released
here but i released a hackless version in the 'Template Modifications' forum if you would prefer that.
3/ I can show you how to position the IP / Report links under the sig if you wish?
