We have several tags that are variants on customise and configure. I don't see these categories being useful, as the questions are already grouped by their subject (the program being customized/modified), while user expertise in customization qua customization doesn't make sense.
At first I considered a rename/merge to configuration until I saw the above issue. If there was demonstrated need, we could have a configure-scripts, but I don't see a pertinent use case for configuration. If you disagree, at the very least we should merge the configure/customise tags into one.
