Hi all I thought I would raise awareness again of this as it seems still no sign of the REBORN client release.
MMDL auto MAP downloader is fully working !! and uses the AA map database to find maps on custom servers you don't have and automatically downloads them for you.
You can download the mod here -: Please read the additional comment at the bottom as it helps make the install easy 
The creator of this VATEC6000 was planning on releasing an updated version but hasnt been online for a while hope the dude is ok and many thanks for this great mod.
So the only downside is that it does not download client mods that are required on some custom servers but any server with a custom map no problem !!
Please pass on this to all you know who play MOHAA lets get the good all days back and enjoy all those fantastic custom maps !!
