The title says it all… But here go a few words of explanation:
In the early days of Wikidot the business model assumed that users will be allowed to create free Wikis but in exchange they will have to allow displaying some advertisements that would benefit us directly, not the authors. They would also have an option to pay some amount of $$ to get rid of ads.
But then we thought: no way. This is not how it should work. Although this is exactly what our wiki-competitors do, we do not like this model any more. Perhaps it is just time to be different from everybody else is doing. So a few weeks ago I have removed all the parts of Terms of Use and FAQ that mentioned ads and the lack of ads is also mentioned at the Features section.
So… your wikis will remain free and clean (from ads) as they are now.
There are some more things coming soon and I promise you that you will love it. They are the reason it has been a bit quiet here recently.
good luck! - michal
