The Wiki home opens with what OpenVibe.Wiki is for (plan T11, D92; openvibe-shared v2.3.1 showcase): 'Knowledge, with sources', where to start (start a space, or sign in to), and the six things a space gets today (page trees, revision history, citations, Community discussion, roles and visibility, search and feeds); the spaces and recent pages follow. The kit's stylesheet is linked on the home only. Home budgets raised as a decision (html 27.5 KB, css 18 KB). Suites green.
