* Post at least 25 times in some other areas of this forum. They must be substantive posts.
EDIT: I forgot to mention. It takes an hour after your 25th post before you get rights to post here. It's all automagic.
* Be designated as a Distinguished Member, Content Expert or Admin.
The former is up to you, the latter is up to Jim, Ed or me.
Note that if you're asking about horn value, all members have access to post in the "Value" area.
