Looking for two mods !!

[Reef Man]

Hi, I am looking for two mods:

1.- Information to be filled in a thread.
I have a forum that we use to sell and buy.
I want to establish in this forum, some fields that must be filled to permit the post to be published, like:
-New or used
-Price
-Time of usage
-etc...

It must be just for that forum. I remember I saw a mod here in the past to do this, but I cann´t find it.

2.-Do not permit 2 active post in same forum
This is for the same forum, where a person can not publish a new post if he/she already has one post open in that forum.

Thanks in advance for the help !
