Understood, but @Daniel hasn't been here since the 20th. My suggestion was to entrust at least one other member with simple admin responsibilities. I'll shut up now .
I agree that it's not good if only one person can administer the site, so someone should be promoted with high level admin rights, but I'm afraid that is again something only he can do
With the dedication I've seen from the moderators here, handing over Super-Duper Purple Attack Knight rights to one of them doesn't seem like a bad idea. There could be a more complicated detail I've overlooked, though—who knows what future plans are set for this place? This is still very much Daniel's baby, and he might be understandably protective of some aspects.
Access right is one thing, the required technical knowledge is another one. Maybe that's the cause. The XenForo forum engine supports several captcha add-ons so Daniel has many choices : https://xenforo.com/community/search/5956467/?q=captcha&t=resource_update&o=relevance Now I shut up too
