Absolutely no-brainer and already on the works to migrate my 5+ WordPress websites onto WebWave.

Just 3 cons I can think of:
- Ability to upload files to root folder (i.e. txt files
- The possibility to alter the CMS page head tags
- Be able to manage your domain settings (change non-root / www pointings)

Albeit none of this is a dealbreaker for me, it could be a whole lot easier to have those features.

Aside from that, it's a 5-tacos pretty well-earned.
