Personally I find it hard to believe the 'list' exists at all. In the absence of any evidence that any suggestion is being implemented or declined . I was always under the impression that the phrase  'I'll add it to the list' is just a way to finish the discussion in a suggestion thread.You say site improvements are related to members suggestions, but I have never seen it mentioned it came from the suggestion box, or credit given to the originating member.
If the list does exist keeping a public suggestion system or a wiki as suggested in this thread is a minute addition to the work already involved with keeping a 'suggestion log'.
As this is of general interest, not only to rutra, instead of him asking admin privately, perhaps you could ask the appropriate people to give the list  to you to post here (or they could post it themselves).
Publicly spirited people who post suggestions to improve the site deserve to be shown some respect and informed about the results of their effort.
Thanks
