There are 3 ways to make a post wiki:
- moderator/admin can make a thread wiki
- trust level 3 members can self-wiki (by using the wrench in the ellipsis menu after their initial post)
- admin can set a channel to have all new posts wikis by default.
I increased your trust level to 3. You can now self wiki. Unless you want anyone be able to mess with your collections, in which case I could make all threads/topics wikis by default for your channel.
At this time, the settings for your channel specify only you can create new threads but everyone can reply. Again let me know if you want this to be changed (read, reply, create are the possibilities but the settings apply for the entire channel.)
Unfortunately, configuration of channels cannot be delegated. Only admins can do this. Until i find a way to give curators more rights over their channels, this is how we have to proceed.
