Haven't been here in a while.  I thought I remember a bunch of different SONAR forums, for different versions and such.  Now I just see one and I had to wade through a bunch of single sign on stuff.

Things change. All the Sonar forums have been joined together.

If you have a Sonar any version related question this is the right place. Welcome back.

Ah ha.  Fine by me.  I kinda hate forums that are super segregated into Discusions of Strange Buzzing Sounds That Happen on Thursdays, a sub discussion with almost no traffic, and pity the poor sod who posts in the wrong forum.

If one of the mods thinks the post is in the wrong place they'll move it but there's no angst about such things.

Cool.  I've seen some "post shaming" tho...

This is the right place for SONAR related questions or enlightenments.
 
If you have a reproducible bug and others have verified it then the Problem Reports Forum is the place to report it.

If you have a song to share the The Songs Forum is a good place to showcase your work.
 
For off topic but music related discussion you may find the Coffee House a place to chill out in.

All the other forums Hardware, Software, Techniques and others are pretty self explanatory. 
 
Take your time and read the Code of Conduct for the respective forums it will save yourself and any others potential grief or disappointment.
 
PS Welcome back.
