What does the Created By column on the question list page really represent? Is it the date the question was asked or is it the date of the most recent answer? My preference would be a date that is both, question asked date if no answers and last answer date if there are answers.
We really need some way to tell if there are any answers that I have not seen. The SAP forum does that by using gray text for questions you have seen all the answers.
On the Create Question page, you choose a 'Group' (InfoMaker, PowerBuilder, etc.) but on the question list page it is labeled 'Category'. This should be consistent.
The question list page has a column 'Votes' but there seems to be no place to vote. I'm not sure the purpose of voting on questions would be.
