The "How do I...?" forum is helpful and all, but a lot of the questions seem to be asked repeatedly by newer users of Construct 2. A lot of these questions are also answered repeatedly by various members of this forum.
Why not have a wiki? Could call it the Construct 2 Cookbook or something like that, where working solutions and .capx files are posted for various problems.
This would reduce the number of 'beginner' questions in this forum by a slight amount, and answers are not longer about answering things that have been answered multiple times and instead pointing to wiki links. Once a new user realizes there is a wiki, he/she will probably post less questions overall and refer to the wiki instead.
