Q:

Would B & CG be a good candidate to replace the GameSquad forum "Advanced Squad Leader Rules & Errata"?

To all ASL enthusiasts (and others). While it may seem arrogant to question a set standard, it is certainly not meant that way.
The current ASL Rules & Errata GameSquad forum contains a massive amount of knowledge about the rules of the ASL system. Because of this, it serves as an important source of information within the community. However, the "serial" character of the classic forum concept has some disadvantages in certain cases of which the following are most important:

Threads often wander off-topic
It's difficult to distill the final answer from long threads due to replies that are not answers to the questions
It's difficult to see if there IS a final answer to a question at all
Tagging is not possible

In my opinion the stackexchange concept is a much better way to build a knowledge base of ASL rules questions, that has more value on the long run. And with having more value I mean not having the disadvantages mentioned above.
Argument(s) in favor:

The stackexchange concept (voted answer, reputation system, meta site, etc. etc.) instead of the classic forum concept

Argument(s) against:

B & CG "generic" tags cannot be used for "ASL specific" tagging, so it's useless for that purpose
The rules questions will be separate from the other ASL GameSquad forums
There's already too much knowledge in the current forum
The current forum just works

Your opinions would be welcome.
N.B.: This proposal only concerns the Rules & Errata forum, the others are fine as they are. 

A:

the "serial" character of the classic forum concept has some disadvantages 

If those are the things you're trying to defeat, that's exactly what we created this software to defeat, too, so it is a very good match.
