yes i did that and also looked in "product-thread_thumbnails_v2" which adds another parameter to the thread(picture) and searched for "validfields" but found nothing.

in the file class_dm_threadpost.php there is three functions which using the validfields array, i need to add fields just to the class vB_DataManager_Post or to all of them ?

"in threaddata_start, you add them" where is the threaddata_start ?

in the function i posted above ?

and i have no plugin, what does it mean in my plugin ? in what file ? newreply.php ?

isnt some guides for this ? i read alot at the articles but still cant figure out...
