Hi,
In my content profile I have a field called "About". This is a very basic textarea so that people can say a little bit about themselves. I'm using Drupal's default "Body" field for this. (I decided against CCK for a number of reasons)

My question: Is it okey to use the default Body field, or should we create a separate CCK text field for this?

Why am I asking this? I just need to be sure that there will be no problems in upgrading to Drupal 7 in the future if I use the default Body field.
-------------------

Similarly, I tried to use CCK Content Taxonomy field, but it didn't work with Hierarchical Select module, so I left the taxonomy fields where they would normally be in a drupal node: in Vocabularies fieldset. Will this present problems when I upgrade to D7 ???
