Any time
Constantly I see the problems happen from logic problems of the current UBBT realisation and limitation MySQL (especially absence of triggers).
For example, these scripts resolve problems with value of fields B_Board, B_Main, B_Status and so on.
On Oracle, Interbase etc. I prefer to fill these fields by trigger "BeforeInsert" or "AfterInsert" according to values of equal fields of parent post - this variant is fully "automatic" and don`t add big advantage on server or client. You may realise in addpost.php checking current values of this fields in parent post before recording in table answer post...
So I am trying to correct hot problems with available for me tools.
