Perhaps we could shift focus a little and just consider the Farming clan as a temporary place for Elder members who want to farm - focus on temporary and Elder. It could be setup as invite only and not considered or used as a feeder clan. Because of this, the membership would be kept small and the ability to come back to clan 1 or 2 would be much easier for the main clans to absorb. Also, because it's elder only, there's no issues with staying in touch because they'll still be active on the forum.
A secondary use for such a clan could also be for Elders who know they won't be able to play for awhile but would like to stay with the clan... Medical issues, crazy work schedules, military deployments, family crisis, ect. The last thing I want to worry about or have my fellow Elders have to worry about is their donations and activity when facing any of the above situations.
We lost a valuable Elder last week because he felt like their was too much pressure to donate given his limited time to play... Despite whatever he was facing last week, Nt still managed to log in enough to donate at least 200+ (that I saw and probably more). He put this pressure on himself because he didn't think he could keep up rather than any of us saying anything to him... Heck, my one conversation with him was supportive for him to not worry about it, that we all knew he was a solid member/elder. If we had a Farming clan/Holding clan for Elders, he could have joined that until he had more time to play and just kept us updated in here from time to time so we knew he hadn't lost interest in the game.
Just some thoughts thrown out for group consideration...
