Some things I would like to suggest to make the influence of opinions smaller:
- When people ask a question, automatically tag the question with the current Tibia version. That way you can always tell which version of Tibia it applied to, and whether or not it's still valid. This is helpful for both opinion based questions and fact based questions.
- Allow opinion based questions, but make it easy to filter those out (or even turn them off by default, and allow people to manually turn them on). That way you keep the platform "pure" for those who want it, but also allow some flexibility.
While it may not have been the intended purpose to turn this place into a forum, somewhat opinion based questions appear to be what people are most interested in right now. It would be a shame to turn down everyone's interest in the platform right now. Fact based questions are pretty hard to come up with right now anyway as you can find almost anything on TibiaWiki or other websites like it.
