I have created a couple of new folders under the category of "Modifications".
They are still under testing, hopefully we will be able to consolidate specific threads/questions/answers into each specific focus, so that topics will be much more easier to find.
Please be patient while we filter out the HUNDREDS of threads in the "BMW General / Technical" folder into the proper categories. Yes, we know there are ALOT of folders right now. But we'll be reducing that. 
This process may take us till the next month(March/April) or so, but trust us, it will be much better and easier to surf for the information you want.
We do hope you continue to enjoy our forums, and do remember to feedback your thoughts, suggestions and comments.
Cheers!
