If it were the other way around, and you were running a free site, would you then not be complaining about having a message about upgrading?
The way it is, gives you more flexibility, because it makes no assumptions about the way you want to run your site, and you can change the message to suit yourself.
In many instances, messages also appear duplicated, but they appear in different parts of the system, and whilst it may appear duplication of effort, it makes for more customization.
What is suitable for some will not be so for others, hence we all have the juggle our settings and messages and especially layouts, otherwise every site looks exactly like every other vldPersonals site.
