Hello all ..
Talking about mistakes, I just did

the article today about Time magazine should refer to IT'S ALL IN THE FAMILY instead of THE FAMILY'S FIRM ( I want to put crying emoticons but I cannot find it ... T-T )
Yup John, would be good if we can edit the article instead of re-submitting the article, it would be a waste of space.
My suggestion at this moment :
1. Edit tab for shared article
2. I wonder if you have a 'life cycle' for an article, means that after a short period of time, the article will be out of screen, saved in AO 'library' .. and maybe you can do the same for forums, whenever an inactive forum meets its 'life cycle', it will be closed and stored in AO archive ..
That's all so far, hope to see more improvements coming.
