My main suggestion would be for the CT and other TSR staff to start re-engaging on the open forum like they used to. I can't remember the last time I saw a red name contributing something light-hearted, or even just showing a bit of their personality. It's now either moderation messages, or those ghastly 'let's all get involved in a fun game, children' type posts.
If the CT has changed into a more 'behind the scenes' role focussed on moderation and business decisions, and more general posting is either discouraged or just not something that they have the time or inclination to do, then that's fine - but I think it needs to be made more explicit. Otherwise, the CT seems to be part of the forum but not part of the forum at the same time.
Another good thing would be an up-to-date list of the names of the principal CT and a brief description of what their job is. Avoiding jargon here would be welcome - as has already been pointed out, what in earth does a 'Community and Engagement' officer do? Clear, plain-English descriptions of roles with names attached would help make the CT seem less 'ivory tower', which they never were before.
