How can I stop users from editing one of their own posts ?

[mihai11]

Hi,

I don't want to forbid editing posts per thread or per forum, just per post – more precisely, the first post from a thread. The reasons is that the first post will be created using a form (not the VB standard input) so the information from the form must be formatted in the same manner in all the threads.

How can this be achieved ? I am thinking to do it with a plugin that will check if the post that the user wants to edit is the first in the thread and if the thread belongs to forum "abc". What hook should I use ?
