I searched what I could, but something is still not clear to me:

a) what was invalid on the post? Everything I think should be there there was, when I compared it to other right reps I gave, they were the same. Why did it happen about 20 days after I posted it? *SourceBOT* sent it, which is probably a bot,so it might do a mistake?

b) why is there no more *users sourceop forum rep page* under peoples' profiles as it used to? How do you check reputation quickly, other than searching by user's created topics?

Thanks for answer(s)
