If I want to contact the EC I either go via the Secretary's email address, or through the mailbox marked “Secretary”. Depending on my request, I get a timely response.
Previous posts about letter boxes have shown that for some developments there are no secure mailboxes, so in that case, wouldn't it be a better idea to just have “generic” email addresses for each member of the EC, or even one email, so at least people know how to make contact?
I have never been in a situation like yours cbf as I am only living in a small, eleven villa development, but surely your EC could at least get expenses back.
If it really is a bad as you say it is, why not sell out while the going is good and have some peace? It sounds like you are in a losing battle where you are now.
If not, how about some positive posts about why you are staying there?
