OSM is a live database, and you should not enter "test" data. If this is a real feature, it should be tagged appropriately; otherwise, deleted.

Hi again
I see in this and other changesets, you have added maxspeed=50. Curious to know how you determined this ... is there a posted speed limit sign? Never seen one in my time in Nairobi.

Noticed that this changeset had moved Jamuhuri Primary west from where Map Kibera had surveyed it. Assume this was an unnoticed mistake when editing. I've since fixed the error, so just letting you know.
