Markdown problem 1
As I understand markdown you should be able to enter raw html. However, when I tried to make a <table> with some information about one of my projects, the Octupus Deploy server responded with an error, ala: “A potentially dangerous Request.Forms value was detected…” Of course this is due to standard asp.net request validation, but I propose that no user input should result in a server error. It might result in an informative input error but not a server error. Expected result: Either the table tag should be html encoded or even better, be rendered as i typed it. 
Markdown problem 2
After my table failure I tried to format my data differently. However the following input does not render correctly according to the markdown syntax page (note: first 2 lines ends with 2 spaces):
Head1: Value1
Head2: Value2
Head3: Value3
Expected result
Head1: Value1
Head2: Value2
Head3: Value3
Actual result
Head1: Value1
**Head2:** Value2
**Head3:** Value3
Note, your support system handles both these cases correctly… See above and below. 
| Head1 | Value1 |
| Head2 | Value2 |
| Head3 | Value3 |
