Short of just PMing each other within a group that wants to share the info, the only other way is to also have an account on a more technically oriented DIY site where you can reference others that want to share that type of information. I also think that it would be a good idea to have a technical discussion area where people can discuss and share ideas on a higher level but RJ has his reasons for not wanting to go that way and this is his site and a good one at that.
