Which php file does save (INSERT) the joinForm datas into the ow_base_user table? I searched it for a while, but couldnt find something. I want to save an aditional field in the table which should to be filled automatically in the background while the User registers on the Join Page.
What I excactly want is to save the md5(username) in that table; so I want to generate this just before the data is inserted to the ow_base_user table.
Which files do I have to change? Also maybe other tables to?
Can you please help me out? Maybe you have documentations or you know this? It would be great!
