Is it possible to run one copy locally with xampp to play around while one copy is running on a server for the public? And which wiki system would you recommend to use in combination with xenforo? I really would like a wiki with some good wysiwyg editing. But i guess there is no possbility to integrate wysiwyg editor from xenforo in a wiki system so that both use the same? And another Question: if i want to upgrade the forum in 5 years, is it enough to buy the 40 $ 12 month support or do i have to repurchase the whole licence?
