A few months back I compiled a list of mobile developer support sites by carriers and handset manufactures, which seemed to lack a direct pointer to Forum Nokia web site (silly me).

There are however a number of general-purpose Java ME and mobile developer (support) and community sites, which are worth mentioning. In no particular order, alphabetical order is too hard for me :-)

wireless.java.sun.com

ericgiguere.com

http://www.java-tips.org/java-me-tips/ (Thanks Shylle!)

j2medeveloper.com

j2mepolish.org

meapplicationdevelopers.dev.java.net

mobiquil.com

javaverified.com

j2me-device-db.sourceforge.net/pmwiki/

www.microjava.com/

phoneme.dev.java.net/

www.developer.com/java/j2me/

Most likely there are many more relevant sites for mobile developers out there, so if you know a good one, please do not hesitate to point that out to me.

I do not usually have much time to rate these sites, hence also recommendations of the best ones are welcome!
