Many tech. questions can be answered from threads in the community archive. I-BMW Members who have posted past replies and exhausted technical query discussion won't be keen to do repeated contributions, when a search of the community archive can give up the valuable answers needed.
If the community forum can 't become integrated into the new technical forum, why not put a sticky link in the technical forum so questions already answered can be found by a search. I'm sure members would feel help for new questions more worthwhile than covering old ground.
