Categorize Threads

[Rachael]

Hi all,

I have a very large forum with dozens of sections which works well. However, every thread in any section can also apply to a generation or age of car. A lot of my users only want to view threads relating to certain generations and I do not want to replicate my entire forum structure for each generation. A lot of threads are also generic and apply to every generation.

What I was thinking was is there a way a user can tag or categorize a thread as belonging to one or more generations when they post and then other users can filter on this if they like when viewing or searching?

I guess I'm trying to organize my threads with an additional dimension to the existing forum section structure.

Many thanks,

Rach x
