Considering buying vbulletin. Post field statistics.

[grmngmz]

I?m hoping to buy a license of Vbulletin but first I wanted to confirm if the following mod exists:

- Posts on the mod section (i.e. https://vborg.vbsupport.ru/showthread.php?t=328256) include fields such as vB Version, Released, Last Update, Not Supported, Additional Files, etc.). I was wondering if there is mod that would require a user to fill an obligatory field before publishing a post, for example "Amount of product". Once I have several posts that have filled this amount, I would need to have and display the sum of all products which would simply be the sum of all numbers entered by the users who have published a post and filled the "Amount of Product Field".

Is there something like this?

Thank you in advance!
