How to count messages according certain parametters.

[ricardo-c]

I want to show in the postbit a counter that shows the number of messages posted by a user, but only in one specific forum or with a specific prefix.

Let's say I have INFO prefix I created and I want to have it displayed in the user postbit so everyone sees how many information posts he/she did.

Here is a screenshot where the counter displays how many XP prefixed messages that user posted. Then indicates how many in the last month and year.

I couldn't find a way to solve this, and vb activity doesn't have the options for it?

I know it's not easy. Or at least any plugin or product that does something similar so I can modify/edit and change so it can display the number of messages with a determined prefix?
