So, you're saying I should not have posted this solution at all since I could not post a link to the thread (did it twice and found my response deleted)?

All I'm saying that if Sergey has published an excellent solution, IMHO it's a perfectly proper professional response to give him credit by pointing to it.

From what you're saying, it does sound as if there are rules against this in some venues. I can imagine why they might set such rules, and I do support their right to make such rules and for members to decide whether they wish to participate on that basis. I suppose it's like a bar or restaurant- owners are entitled to set a theme and if you turn up, you're expected to be OK with that. You can't go to a Mexican restaurant and demand sushi just because it's healthier. ;-)

I can't comment any further except to say that you have been welcomed and supported on UT which does allow you to reference excellent answers elsewhere if you need to.
