Finished search feature yesterday, improved it a bit today, and now also the tagging system works more or less as intended. All users can edit their own video clips' names + tags. All users can add tags to other users' clips. Now I guess I need to improve search capabilites/possibility by other search engines. I don't quite know how. Should I list tags below each videoclip in each users vlog? Or only list tags in the RSS-feed? OK. Maybe I should wait with this, and go for trackback support.
