In my opinion though, what I only even see useful for me about someone's posts page is 'notify', I can not use it for any other reason like 'quote and reply', I find those not useful, but better to be there because other forum members can see it useful, but I have not and have never thought of using it before.
I get the clearer picture of a thread before I will want to merit a post, also before I can reply to a topic or someone's post, I will like to visit the thread directly so to avoid repetition and also avoiding posting what others have posted before.
Please, I will be glad if you could share that link here, bearing in mind I'm referring to the "Delete" button issue. I will like to read how the issue was tackled from the perspectives of other posters.
What I can suggest is for reply and quote button to be removed as it can even encourage spamming as to not reading what others have replied under such post, I believe good posters will visit the link, check the thread before making any quote or replying. But if delete button is added including notify, this will really be good. Just only delete and notify button will be fine while only notify button will be fine if it is another users post history.
Or, maybe, 'report to moderators button' can also be included for easy means to report spam and plagiarized contents.
