although this has some restrict. But I think it very ok. your idea?

If you want an integrated wiki, this is the tool. Notifications linked in with the forum, exceptional integration. Takes some time to set up the Areas, but for a roleplay forum its perfect.

On the other hand be prepared to get your hands dirty. Pegasus provides exceptional support but it does have the odd bug than needs a manual fix. One of these so far was significant.

I love this product but if the developer left I would almost certainly have to remove it and migrate my content to another wiki product with cross authentication.

Anyone have idea like me???

If the parent company disappears and responsibility of development is not transferred to another entity, VaultWiki becomes open source. If there are no more developers at the parent company, and a new developer is not hired and/or the parent company expresses no interest in continuing the product, VaultWiki becomes open source. As far as I know this is discussed in the License Agreement.
