How about a lobby, which only recognized clan leaders (or their designated Emissary) could actually post in. This would allow the announcement of new members, of recruitment, of tournament, leagues, etc . . All without some of the negative interference you see in some MP clan forums on major official sites. It would be easily moderated, if necessary and it would be a central place to come for clan news and happenings in the MP community.

I think a section to post AARs would be nice as well as another section to post replays and screenshots of battles. This would allow for some interesting discussions on maps and how best to attack/defend and other such team tactics.

Clans are doing a disservice to the MP community by not discussing such things. People who might stay around if they were able to learn such information now just get frustrated and leave since they don't stand a chance of winning, without such info. It all leads to a smaller MP community and one which eventually dies away.

I would rather be an average player in a very large MP community than one of the top players in a very small one.

Besides, if you TRULY believe you are skillful, you do not need to hide behind secret units/tactics/etc . . You will win anyways. Why not share things with the community as a whole?

It all leads to a better, larger, more-competitive MP experience. That was another reason why STW and MTW were so well thought of. They were very large MP communities and most clans were willing to train new players and show them all the "secrets". It didn't kill any clan's success. There were more excellent clans during those times than ever.

Good luck in deciding.
