• “Dismiss” link to stop tracking each post
• Paged display table
• Re-definable constants(in code) to modify array outputs.
  • MY_COMMENTS_TRACKED = `if (count($LatestCommentsList) > MY_COMMENTS_TRACKED) { unset($LatestCommentsList[0]); …}` during a comment save a blog_id, post_id pair is entered into usermeta->LatestComments, the total counted and when the array exceeds limit, the oldest pair is deleted = 100
  • MY_POSTS_APAGE = more posts per page = increased work for CPU = 10
  • MY_COMMENTS_APOST = more comments per post = increased work for CPU = 1
  • OTHERS_COMMENTS_APOST = 1
  • POST_EXCERPT_LENGTH =`$post_output = wp_html_excerpt($post_output, POST_EXCERPT_LENGTH);` 400 chars
  • COMMENT_EXCERPT_LENGTH = 250

Performance notes: tested on a small WPMU install(>200 blogs). I have not seen how this version performs “maxed out” on my own install yet. I do not know how this plugin performs in a large install. An array of “Blog_id, post_id” pairs are stored in usermeta->LatestComments to a defined maximum, called then sliced by page number, looped to retrieve posts, then each post looped to retrieve comments – “My Comments” and “Other comments”. The bottom of the My Comments page has a numqueries count, FYI(if SiteAdmin). Redefining the MY_POSTS_APAGE constant can throttle the page.

Known Bugs: redefining the MY_COMMENTS_TRACKED constant to a lower limit after users have “maxed out” the previous limit will only unset one comment after each comment submit(“update_usermeta(…)”) thereafter. Such users will continue to exceed MY_COMMENTS_TRACKED Limit until they “dismiss” enough comments to be below the newly defined limit.

Install Notes: drop in mu-plugin, monitor performace/cpu load as “usermeta->LatestComments” data fills with each user comment submitted to defined maximum(MY_COMMENTS_TRACKED). I have not tested this revised version under heavy load. Happy testing!

Competition eligibility note: this plugin is a significantly revised/enhanced/twisted version of WPMU-User-Comment-Tracking-and-DisplayThis work is Copyright GNU GPL You and Your Loved Ones. And: – Xiando (Oyvind Sather), who originally wrote it – And D. Sader - and is intended to add similar functionality(with a few twists) as Matt’s popular wordpress.com My Comments feature. On that basis, I’d accept a decision by the judges to exclude this plugin from the contest.
