If, at creation, one indicates that a wiki will be used for business, the upgrade options are extremely expensive - a far cry from the reasonable prices for "individual" wikis.
In my case, I need a wiki for a short project (6 months) and could do with some extra file storage space. I don't however need all the "business" features, and I don't want to spend the 500-or-so USD.
Next time I create a wiki, should I just pretend that it is for personal use (and have the cheaper upgrade options connected to "individual" wikis)?
For a new wiki I'd like to start, the only premium feature I want is the custom domain but paying $100/month for that is pretty steep for only that feature. Do you have a-la-carte pricing for just the custom domain feature?
