I recently learned a valuable lesson regarding VBulletin forum script licensing. A couple of years ago, I started a forum using the VBulletin script. I paid for the license and everything was fine, then recently I decided to cut bait with the forum. I needed some cash so I unloaded it at a near give-away price.
When I sold the site and attempted to transfer the license, I ran into trouble. I learned that even though I bought and paid for a full license, in order to transfer the license I had to be “current”. My active status expired 1 year after purchasing the license. I had to shell out more $$ to get the license active again, so that I could transfer the license.
A valuable lesson indeed, rather a costly one as I more or less gave the site away.
