Found out recently (like these several days). When I need to post some pics, I must use "preview" to check the post first, otherwise if I just click "post" or "add reply", the layout of the post will be weird, sometime even two consecutive replies will get mixed and messed up (Example Post).
And it seems that I cannot edit the post, so the whole thread just stays messy...
I tried this on two diff PC with diff OS and diff IE, same problem happens. Is it a website tech issue?
