Unfortunate Circumstances

After everything is done and implemented, how easy or difficult would it be to make changes, such as adding in forgotten or overlooked things/options? I mean things like search engine criteria, adding categories for types of music and such for the directory. Adding new sections to profiles.

In general, the last phase will include "bug fixes and miscellaneous", therefore small changes will be possible. The directory will have auto creation of new categories based on what people input in their "tags" so that shouldn't be a problem. And as for addition of new functions, if they are minor, it should be no problem to implement. Anything major would have to be a whole new project, meaning, additional costs, and an additional documentation.
