I am having one proposal.

We have the following:

Sub-Forums : 'Non Related Discussions'.
and inside this subforum we have 'Commercial Trading Systems and indicators' section.

So we may have 3 sections inside this 'Non Related Discussions' subforum:
- Commercial Trading Systems and indicators.
already exist.
- 'Commercial Holy Grails'.
We have many commercial systems which may be identified as a grail so we need just to move some threads from commercial section to this commercial grail section.
- 'Public Holy Grails'.
I will move some public threads to this section which may be identified as a public grails (some systems where authors claimed big profit for very short period of time or some unrealistic in normal point of view but public ones). Anyway ... who knows ... may be someone will create some public system with 1000 pips for one week ... we never know right?

People will always look for grails, for perpetual motion ...
So, they may do it in their special section with public and commercial subject.

Forum will be cleaned from grails including commercial ones, and people will have a right to develop/sell them in special place on the forum.

What do you think?
