Why are my points reduced and how to add an attachment to a forum thread?Just now, I recalculated my points and found that 4 points were reduced from my yesterday's contribution of 66 points. Then, I visited the top performers page and was shocked; it is showing yesterday's points in today's column and day before yesterday's points in yesterday's column. But now, the 'Top Performers' page is showing correct information. I took the screenshots but I don't know how to add an attachment as I couldn't find the feature here. I would like to know the answers to these queries.
1) Why are the four points reduced?
2) When will the ISC date change and when will the Top Performers page change accordingly?
3) How to add an attachment to a forum thread? Is the feature unavailable now?
Note that I am not disheartened for the points reduction. I just want to know the reason behind it.
