I like the concept of using the Google wiki. In addition to the "Google is Good" factor, there is the likelihood of very high reliability and zero cost. Also, it seems appropriate due to Bram's work.
As has been pointed out, spam is a really big threat, and will get worse (more automated) every year. I don't see why we should ask anyone here to take on the job of manually removing junk. The problems of using the Google wiki may be a benefit in the future. How about this concept: Use the Google wiki with a dozen admins. Those admins are likely to be here, and either have a Google ID or would be willing to get one. Create a new mailing list ([EMAIL PROTECTED]), or use an existing list with a convention that the subject should start with "vimtip". On the wiki, explain how to post a tip by emailing the tip to the agreed mail account. That would require the user to join the list. Alternative: Have an automated account that forwards any mail including "vimtip" to the agreed mailing list. A discussion here would then massage the tip and decide its fate. Perhaps it is too similar to an existing tip, or perhaps it should be incorporated into an existing tip. After a week, a kind wiki admin would post the final tip to the wiki. ---Benefits--- No spam on wiki. Each posted tip will be massaged and worthwhile. Tips on similar topics could be arranged together. Someone with a tip doesn't have to worry if it's "good" (it will only be posted if the community likes it). That might encourage tippers. ---Problems--- No WYSIWYG editing (might be a benefit - uniform style). Burden on community to edit tip within a few days (and likelihood of unresolved arguments). Burden on admins to post tip. Some tippers will be offended when their work is edited or rejected. That might discourage tippers. John
