my users are getting an error when trying to mark the best answer.

Can you copy and paste the example of the url which is being generated for marking the answers, as well as the a link to the thread it's being generated for? Also, what version of php are you running?

wow, thats a great one,

Just like Yahoo Answers, Can you make an add-on product about which user has posted most best answers and so on..?

Neat idea, will definitely consider this.

PM sent. FYI, admins can mark best answers.

very nice one mate! I like it!
Installed and nominated!

Works just sm00th on VB 3.7.3 ;-)

//Suggestion
- Would be nice to see a "Answered" also in the Threads-Overview, maybe next the "rating" on the left.
That way we can see which threads already have received a proper answer. ^^

Would like to have the option to disallow thread starter from choosing self as best answer.

very nice mod .. just like yahoo answers :) may be MOTM?

^^ Definitely going to be added :up:

I was thinking about it, but figured the only reason a member would have for doing that would be if my any chance he was able to get an answer from another source, at which point a link would probably be provided. However, i will consider the option of restricting this.

;)

It would be interesting to give users the option to designate a thread as a question in any forum rather than setting any one particular forum as a Q&A forum. That way we could have regular threads in all of the forums, and those that are question-based could benefit from Q&A layout that this hack gives us.
