Hello Zaynab, hope you're doing fine in your exams

Regarding the first question, well unfortunately this error is out of our hands, it's a problem in the hosting server for BCMF but the good news is that it's being worked on, hopefully it will be resolved soon, and as the guys said, the messages are usually sent.
And regarding the second question, well yes, sometimes we correct, not just by moving the topics to their appropriate place, but also correcting how it looks and the font layout too, you can check the many help topics found in this section (The BCMF) for how to appropriately change the font and layout when posting.
If you post something and you want to correct it there's the
Edit button found on the top right of your posts which will allow u to edit them

Hope that was clear enough, don't hesitate to ask if you need anything more.
Take Care
