How to create a vb5 extension

[epagesvb]

Hey guys,

am i just blind or are there really no tutorials out, where is explained how to create a simple extension? I did not find any documentation regarding vb5 extensions on vbulletin.com as well. Can i just create them like the ones for vb4?

Someone has a good how-to in mind to start with?

Maybe i just tell you what i want to do - i want to create 4 post-tables for every thread. In each table there is the data for one language. In the frontend i need to pull the data from a specific table baded on the language the user uses.
So i do not just have to change some template stuff, but make some major changes to the php files as well. To be honest i really have no clue, where to start.

Could you give me some advice where i should start?

Thanks in advance
