As question says.. a number of reasons for asking same..
1. Many old sites have migrated to other forum software.
2. Many friends whom i came to know via vbulletin, have quit the same.
3. Vbulletin.org is no more fun, like used to be few years ago..
4. Almost difficult to find vbulletin coders/designers for custom work (inspite of good budget).
Or maybe I am wrong.. or following wrong direction ?
