supersleuth – having what removed; the record of the e-mails or the person who sent them?
If the latter, then as the members of the Executive Committee (E/C) are nominated, seconded, and voted for at each Annual General Meeting, then the simplest solution is for you to obtain sufficient support from like-minded owners so as not to again elect the author of those offensive text messages and e-mails.
Of course if there’s been no E/C Meeting where a decision was made and minuted to authorise the Secretary to issue those text messages / e-mails, then those have no authority in any case, and you could pursue that line of response.
Whatever the circumstance, it’s probably better to simply suck-it-up, to ignore the texts / e-mails, and don’t give the Secretary the attention that they obviously seek.
