Great Reply Paul,
Our CC has written on players walls before, we try to research clubs where owners are inactive, as many have said if a member is happy in their club then they wouldn't leave.
I do not consider it poaching there are a lot of players out there not reaching their full potential and some that just don't realise what they are missing, clubs where the owner and directors do not communicate with their members, clubs that post no info or help pages and some that don't even post club tourney's.
There is also the issue where a player may not suit a cubs set up, unless you can freely advertise how your club operates a lot of players are going to be left unhappy and not enjoy all the game has to offer.
I myself received one invite from another cc, only ONE :( although I was flattered was also slightly disappointed received no friend request, game invite, e-mail or wall post, they weren't really trying LOL
Happy recruiting
