I have finished cleaning up the Island Glades area (make most ways conform more to the GPS track, named streets and make new streets). I am not from that area thus there are still some parts which I am not entirely sure of. You can go to the OSM main page and chose to look at osmarender (more frequently updated) layer using the plus sign at the right hand side of the page. Alternatively, here's the URL:

osm.org/?lat=5.391152566925179&lon=100.30088485682742&zoom=17&layers=0BF

Roads tagged with Unknown are the ones I do not know the names. The is still a road I haven't done connecting Jalan Besi to Jalan Tembaga. If you could provide me with the name of the road I will do it.

Also, these are some of the roads (or part of roads) missing from the map:

Jalan Tingkat Besi - Jalan Besi
Tingkat Besi 2
Lintang Besi - Tingkat Besi 2
Solok Besi
Solok Tembaga 4

(and lots more).
