Sometimes votes will need to happen on short notice depending on the nature of the issue. It's best to use a push mechanism where the thing shows up than something that requires people to log into CPDL on a particular schedule. E-mail also works better when someone is on the road and accessing stuff from an e-mail but not web-enabled phone.
E-mail is not reliable due to spam filter false-positives, however, so I would suggest an initial e-mail and also a generic Votes topic in the confidential CPDL forum just so it pops up if someone checks just letting them know a vote request went out so they know to look for it if they didn't get it. There should also be a provision that the committee members can waive the notice emchanism requirement in favor of a another forum (e.g. if the CPDL exec team has its 25-year reunion in some pub), or if something posted turns into an impromptu vote on the forum, then the technicality of the e-mail notice can be waived instead of notice having to be sent.
Given that they attorneys said they'll use the forum we fill out to generate by-laws for us, and there may be state legal requirements about how a board of directors votes, should we hold off on hashing this out or try to get our recommendations to the lawyers as part of the data they base the by-laws on?
