Wanting to maintain Debian packages

[T o n g <mlist4suntong@yahoo.com>]

Hi, 

I had always been hoping to maintain some useful debian packages. Now 
that I've successfully revived some abandoned debian packages, my 
confident is gaining and want to pick up more. 

I took a look at the orphaned package list, to my biggest surprise, there 
are a *lot* of packages that I think useful are now orphaned [1]. 

Is it OK for me to take over the ownership for all of them? 
What should I do? 

Thanks

orphaned since 1385 days.
