Text wrapping is being worked on, when V3 of the website launches it should be resolved.

People with spaces in their names are backers from before V2 of the website if I remember correctly, so any new accounts or name changes can no longer have spaces.

Having to pay for an alias change after your first free one is to stop people constantly changing every time a new meme crops up, among other reasons, for example.

Fire away if you have any other questions. :)
