Sounds like a storm in a tea cup really. Why don't we just have a sub category for "watercooled". Most of us would put up our hands and say we search via "Topic Activity" anyway, and that watercooled would just be another subheading we would read. You can then choose to read it if you wanted, and it sounds fair just to have the one extra topic. After all, it is a VW.
Squiz....
I agree - I don't think it would "widen the gap" (get over it) - I think it would actually bring us closer together. :kiss
The tech & specific watercooled questions would be in that section - but everyone would join in the general chit chat/pics/buying selling etc etc.
Yes, it may take a while to build a following on the forum, but surely slowly when they find there is a place for them, they will stay...
