hopefully it will be released as beta, becasue i just clicked on the main link and i already got 3 errors...
good luck with the hack though
as for the release of vb3 hacks according to what i read you aren't allowed to release any vb3 hacks as vb.org has agreed with vbulletin.com until vb3 has reached rc or gold.
when vb3 has reached a stable version then there will be a vb3 section created and the vb2 hacks will be archived accordingly...
in responce to your conversion to and from vb3 to vb2 then i would suggest you pm an Administrator and ask them because i believe only they could give you the most valid answer...
