I use WampServer to set up my DB, PHP and Apache and do my cleaning from PhpMyAdmin. The megaregions are so easy to move around in that I forget all the draw backs and other temperamental quirks they have. I still have problems with terrain textures, saving terrain and saving an oar from a non root region. I know since all prims end up in the SW this might not be possible. This is a draw back if you want to work and save inside the megaregion but if used as as show case and finished product not a problem and many work a rounds are possible.

The idea of a team working in regions (256X256) and uploading in to megaregions is good even using the same DB for two or more megaregions makes life easy.

The hypergrid part that will in the end connect it all together is also working reasonably well.
Diva thank you so much for sharing your knowledge and hard work much appreciated I for one am impressed at how well this is working
