Creating a postbit sys...how do i make user set? add to vbops?

[sonichero]

Im am creating an entirely new postbit system called postbit_via, as well as other postbits not as advanced

I want people to be able to have their choice of several postbits in which to use, so how would i go about making that an option under user prefs?

I also want to add "Use Via Postbit System" to vboptions under "vertical posbit" option that will enable the use of the postbits.

Furthermore, how can i make the threadstarter's postbit a different template?

Thanks!
