My recent experience

Proposed deletions are for uncontentious stuff that no-one is likely to disagree with, so if you do disagree you can get it back. If it is a proposed deletion all you need do to dispute is remove it from the article, though I'd recommend doing so with an edit summary such as "disputing proposed deletion". If it has already been deleted and the 7 days have long gone, then just ask for it to be restored at WP:Refund. Hope that helps.

Thanks - I didn't know about WP:Refund There's also the "no loss of knowledge when doing edits" campaign, which is a good stance to hold.

That depends, "no loss of knowledge when doing edits" rather sounds like "you cannot remove anything, no matter how wrong it is", which is a very popular credo among Wikipedians. Brya 05:20, 31 May 2011 (UTC)
