Hello,

If you have some spare time and you want to help improve OSM, you might
want to check out the following QA tools that highlight potential map
problems that you can then fix. Warning! Not all problems highlighted by
these tools are actual bugs! As always, please evaluate before blindly
fixing things on the map.

1. Where the Streets Have No Name
https://indyhurt.github.io/where-the-streets-have-no-names/map/?roads#12/14.5/121
This highlights roads that currently have no name=* tags. If they really
have no names, then they should be tagged with noname=yes.

2. Keep Right!

This is one of the oldest OSM QA sites and shows quite a lot of bug
categories.

3. Osmose

categories.

Developed by Geofabrik, this QA tools highlights a other bug categories not
usually seen in other QA websites.

5. Restriction Analyzer

This tool focuses exclusively on turn restriction relations. It highlights
existing turn restrictions, and pinpoints possible problems and warnings.
