-Does google counts subdomain pages/links as external or internal links?
-Can you register a subdomain to DMOZ in a different category than your domain?
Any other way to increase external links?
Thanks in advance!
With a content site it is more likely but by no means a guarantee. The directories forum here will provide insight into this and if you want a captive audience of other ODP editors (there are a bunch that post in the directories forum here too) do a Google search for "resource zone". If you search that site you'll find some threads where some incredibly content rich sites were (unreasonably IMHO) limited to one or two listings.
If you choose to ask about your specific site there, be prepared to accept the answer given by whoever responds. You can be sure lots of ODP editors will look at it and maybe even take notes.
