Data Base Mod?
 

Is there a Mod for a Database for the forum that my users could input data that I specify?

That's a really oddly phrased question. There are many mods that keep track of things, but you need to rephrase the question so we have some idea what you're trying to do.

Be sure to look through all the current mods yourself first. Then we need links, vb version, and a description of what you want to do, not what you think you might need.

If you are looking for something similar to IP.Content Databases then the answer is no. you would need to use IP.Content for that and integrate it with vb using IP.Converge.
