Suggestion: provide a way to add a URL into the 'description' or title of custom fields.

[srl295]

It would be helpful to be able to add a link to custom fields, either as an inline link or as a 'more info' link.

An example usage is something like this, a checkbox that says:

• My employer has already signed a corporate CLA (Check the list here)

Where users may want to check a list of employers before checking the box.
