I installed various wikkis:
-www.babels.org append /wiki or /survey to see them (in other words: for your eyes only! these are not altogether public wikis)
Things I'd like to see implemented:
-stable/default wikka releases that support utf-8
-something like usergroups to facilitate ACL management
- Just saw this: ACLsWithUserGroups. It seems to work!... could become standard in next wikka releases?
Alas, I am not a developer!...
